Jeff, I hate to be a jerk, but if a man came up to me in a restaurant and told me how beautiful my daughters are, no matter the brochure, I'd be too creeped out to respond favorably. If a woman did it, I'd be flattered. Say what you like - that's just how life is.
Now, if you were Lon Haverly, barking a space in the mall, or if I saw you in a booth at an art show, or met you in a gallery, that would be another story.
Brian, I'm a full time pro because I say so, just like Michele pointed out. If a regular employer offered this to me as a yearly wage, I'd be insulted, but since it's mine, I'm pleased as punch. I'm terribly optimistic that something good is just about to happen.
Yes, you need a website, cards, a portfolio, etc. You already have 10 clients, so you have the start of a mailing list. Start doing the things artists do to market themselves, and when you're financially able, go for it. While you still have a day job, study some to determine whether or not you're really ready to go, skills-wise.
Find a local pro and ask them for their advice - are you really ready to go pro? Do you have the skills to sell? You could also get chummy with a gallery and ask them for their advice.
Start going to the theater and city council; go to a church in the monied part of town. Carry a small portfolio or brochure to show people your work, whenever it comes up. Be seen at the art museum, and other cultural happenings. Try to get in the newspaper. Do a painting of the most important/wealthiest friend you have, and then ask them to host an unveiling party, where there will be wine and contracts.
There are contests and juried shows, which are nice. Go to
www.artdeadlines.com to find calls for entry and so on.
Now, I don't do all these things, I do some of them. Mostly I paint, so when I do them, I have a lot of stuff to show that I don't have to make excuses for. I'm at the beginning of my career, so I think of it as though I am building a foundation. When I talk to someone and they ask me what I've done, who I did it for, what my style and influences are, and what "kind" of paintings I do, I want to have a good answer. I have a show soon where I have 12 paintings that all look like they were painted by the same person, and I looked at them and thought, well, gee, I guess it's all coming together.
It sounds like you've made a good start, but you're getting anxious to see "real" progress. 10 commissions is nothing to sneeze at, and you should be able to replant that field and see if something else takes root. Maybe you're already a pro and don't even know it!
