I would recommend The Closing Exchange or Notary Go. They work with newer agents. Please note: they are low ball companies, but they have plenty of work and you can gain experience. Most seasoned agents will not work with them due to their fee offerings. When you are confident in your skills you can negotiate with them for better fees.
If they call you on the phone negotiate everytime. If you are afraid say "Is that the best you can do" ? If they say yes, accept the offer. If they give you a higher amount you earned more money for that signing.
