My impression is that decent firms will pay decent fees, regardless if the notary is experienced or not. The decent firms will try to find an experienced notary, but may use an inexperienced notary if they can't find anyone else.
Cheap firms will balk at paying a decent fee, regardless of the notary's experience. If they can't find a cheap notary, they'll just turn the assignment back. I've had calls from cheap firms and turned them down. Four hours later I'd get a call from a decent firm for the very same assignment. (With small towns, you can tell it's the same assignment just from the name of the town.)
You're not going to fool anyone about your level of experience. You'll probably get every document completed correctly, and the finished package will be indistinguishable from a seasoned notary. But when you are talking and emailing, your lack of familiarity with jargon and customary billing procedures will be a tell. For example, they ask for a scan of your W-9. The newbie sends one dated the same day it was requested. The seasoned notary sends the one she filled out in January for some other company.
