Hey neighbor (sort of)!
My local guess would be the area you are in. You could be a kick-butt artist but a small town with surrounding towns filled with
sign-shops, don't really require anyone to travel to a
sign shop 20 (more like 30) minutes away.
I am sure I will get knocked on for saying so, but if you have no business, find a successful business in town that has the worst
sign/window
signs/graphics/etc. and work up a couple of photos to "redo" the store/shop/etc.. Now go pitch it to the owners/management. If they only bite on a small piece, you got more than you had and you had a chance to sharpen your skills as well. I am not saying to design for free, but if you are sitting doing nothing...
Check out any local business meetings, city council meetings, etc. and get your card in as many peoples hands as possible making them aware of who you are and what you do.
Who were your parents clients? Hit them up - let them know that the service they got then is back at it again.
Is your store front getting attention? (Do you have a store front?) Are you demonstrating your skills to others around through your own shop?
Some ideas...keep at it and don't lose confidence.
