First, doing mobile General Notary Work in CT will put you in the poorhouse faster than any other state due to their LAWS. Which you need to know inside out & upside down before you push that stamp the first time or you run the potential of rapidly getting yourself in a world of hurt as GNW in many ways is actually harder than NSA work because, well, you get a lot of questionable requests, so you really have to KNOW YOUR LAWS. Not just the handbook, but statutes, codes... FORUMS! Also, many NSA companies will ask you to do something illegal as it's not on them, it's ON YOU!
Second, PLEASE, PLEASE, PLEASE check Directories (this is an excellent one) for how much competition you will have, how much business there is and the fees being made. That ought to open your starry eyes a bit. (Do NOT for 1 second think that undercutting NSA fees to get work will get you started in anything but forevermore putting yourself in the bargain bin & broke.) It's not easy to get started, but it IS one of the few jobs that you can 'earn while you learn' as long as you're willing to follow all advice I've given here...and read forums for other good advice.
Third, the BEST education you can get is 'free for the doing'. READ this and other popular forums 'til your eyes bleed. You'll eventually get a 'feel' for the different types of signings offered, an overview of fees you should be charging, what companies to always decline or experience is what you'll get when you don't get paid.
Last, but most important thing you can do is figure out just how far you are willing to travel AND WHAT IT COSTS IN EXPENSES & TIME to each & every town, county, zip in 'your service area' (and realize that work will only provide you with a fairly good 'guesstimate' of what fee will be PROFITABLE as with far too many 'offers', your hard costs will exceed the fee. Know when to say NO! Ditto all other expenses involved...equipment required, paper, toner, annual background checks, E&O insurance, cell phone, AUTO, tolls, taxes...and a ton of other expenses I've not mentioned.
