STARTING A RESTORATION BUSINESS

Has anyone started a business from scratch ? Did you get financial help ? Business loan ? Ive been told you can get government help. Here is my situation. I have been doing body & paint for about 20 plus years part time. I have been doing it full time for 3 years. When i was doing it part time i did out of my dads garage. When he past away we had to sell his house & garage. I bought a house with a 16x30 garage. I have been doing body & paint in it for 3 years. I hate painting in the same bay that i do welding, cutting & body work. I am swamped with work. It is awesome ! I would love to expand & start a business. There is so much more i can do if i had the room. I have turned down complete restorations because i dont have the room. I have heard go get a loan, go get a business loan. My credit is **** only because its been a long time since i have had a loan or credit card. Ive always paid cash for things. I cant show any income because most of the people pay me in cash. As of right now i have 10 people in waiting just for body & paint. I know there are people out there that would love to have my problem. For those of you that have done alot of cutting , grinding, welding & body work in a one bay garage & then try to do a nice paint job know what i am talking about.
