Painting canvases and walls

I'm a painter who's good at his work but I'm not professional and everything I know I tought myself. I'm looking for a Job. I can paint potraits, stretched canvas, customize, clothes like denim jackets and kicks, do paintings on wakks. So someone with a workshop and got extra money to start a business can easily use someone like me to paint some stretched canvas and sell the in art gallaried or in market places for higher prices and thats more profits for them.
