percent with seeking out a skilled & experienced Mentor.
As stated above, Maybe one could dabble as a witness for GNW . . . of course, prior informed consent would be a baseline component if serving as a pro bono witness.
The OP doesn’t indicate what (if any) training/certifications have already been completed. So, it’s difficult to provide clear & concise answers to general, broad-sweeping questions . . .
Anyway, of the mentoring programs I’ve participated in, hands-down, the optimum training & mentoring program would be the very reasonably-priced Notary2Pro team.
As new members seek insights regarding launching their business, a Key Element to Success is providing themselves with an appropriate foundation and undergirding that will serve & support their business.

Over the years of having successfully completed nearly all the available training programs, I only recommend the very Best (see below). This training amounts to a few hundred dollars. Due to the very reasonable price, the training investment can be quickly recouped. This investment is worthwhile & will serve you greatly over time. It will also save you from wasting precious time.
Certainly, we haven’t forgotten our maiden voyage into this business sector nor how very difficult and how long and challenging the climb was to make.
When we were learning, no one handed us answers (unless we paid a Mentor for their insights). We each had to grind it out, make mistakes, learn, correct, and implement a plan of action to improve the services we provide via our businesses 1 at a time.
This training not only provides guidance and instruction regarding providing these services, but also provides MUCH information about how to start, manage, and grow a business within this business sector. In addition, they provide Mentoring services at very reasonable rates.
In addition, there is a great amount of risk inherent while providing these services. The training increases one’s awareness and cognizance of the potential pitfalls and risks that could harm their business before they really even get started. As such, the insights & wisdom amassed during training will serve the newbie business owner very well at the onset and over the long-term.

My personal experience:
When I initially started performing this work, it was unequivocally clear and painfully obvious that if I wanted valid, trustworthy training that I’d need to find a professional training program. The existing business owners explicitly stated that they saw others as the competition.
At that juncture, I successfully completed MULTIPLE training/certification programs including Notary2Pro & NNA and many others. I have extensive experience in skill sets that require certification and recurrent evaluation tests; i.e., I’ve maintained my Project Management Professional [PMP] certification for more than 20 years. So, I understand what it usually entails and the elements that should be included within a comprehensive training program.
Regarding the NNA training specifically, it’s lacking across multiple topics & categories. Many NNA “graduates” choose to take additional training courses elsewhere, because they sense they’re insufficiently prepared. Their primer has errors throughout. Their hotline is less than reliable for accurate responses.
In my experience with undergoing the multiple training programs for certified notary signing agent [CNSA] certification, hands-down without question, Carol Ray’s Notary2Pro training programs are optimum in this industry. I’ve successfully completed ALL of the multiple training/certification programs that Carol offers through her company Notary2Pro. Her programs are thorough & detailed. These also prepare the business owner to operate a business. In addition, she offers Mentoring services. I found those to be excellent & INVALUABLE when I was initially starting out in this business sector. The prices are surprisingly reasonable. 
I’ve professionally compared the training/certification programs available at Notary2Pro with the others I’ve successfully completed. The ONLY training/certification program I recommend is Notary2Pro.
A list of companies that hire Notary2Pro graduates (with minimal or no experience) is provided to successful course graduates. => This list is pure GOLD! Study up, refresh your notes, & let Carol know when your initial few signings are scheduled. She is a wonderful mentor & can be on standby in case you encounter difficulties or have questions during your first few signings. She’s the Best! Her support will help you Build your Confidence in providing this service. 
In addition, Notary2Pro works diligently to keep this list up-to-date regarding vetting and viability. As we all know, some reliable clients can encounter financial difficulties and that, in turn, can negatively impact CNSAs directly.
Of course, your best bet would be to visit their website at https://www.notary2pro.com/ , research, and make the choices appropriate for your situation. The training programs by Carol Ray are comprehensive & thorough. 
P.S. I receive no compensation or remuneration of any type or kind as a result of my first-hand experiential review above.
P.P.S. As Carol has recently passed (February 2022) from our earthly plane, reach out to others on her team please. You’ll benefit greatly as a result.
