That bond seems low. I think it is $75,000 for a full EC license in Florida and the limited low voltage license was $10,000 when I was looking at it 10 years ago.
Anyway, good luck in your new endeavor. I know this is a slow time to start a business but that could be a good thing. It gives you a chance to learn.
BTW if you have a sharp pencil on your schedule C, I doubt if you will really "make" much money for a while.
The IRS doesn't expect you to and if you are good at itemizing your start up expenses you probably won't.
The hardest part of running a business is actually the business part, not the trade part but when you master that you are on your way to a satisfying career.
