So I have been a licensed electrician for sometime now and get alot of customers who want me and only me to do the work. I also get alot of leads and new customers. So with this idea I have thaught about venturing out on my own. My biggest worry right now is getting enough money or backing to start up. IE a van, advertising, insurance, bonds, equipment, stock and etc.

So how much should I shoot for in funding and where would my best bet for getting any backing be?
