Kind've a hard question to answer. I would snoop around to see who the smaller go to companies are for remodeling. Who's always busy in your area? When you find them, contact them with your company info & let them know you're interested in any paint work they may come by. They won't keep you busy every day all year long, but you might hit it lucky & get your foot in with the right person.
With a company I used to work for I hooked up with a remodeler that hated to paint. He started giving me little side jobs here & there, and before I knew it I had to quit my job just to handle the jobs he was tossing me.
Another possible good area would be to hook up with your local real estate companies. THEY NEED PAINTERS. People selling their houses usually need to freshen up the walls to get rid of what others see as horrible taste in colors & wallpaper. Only problem with them is they usually want it done yesterday & aren't always looking to spend a fortune on something they're getting rid of. Be prepared to have a company truck, business cards, and insurance when dealing with them.
Then you got direct mail. If you look into the actual costs of targeting everybody you want, you'll run away from the idea. Try going out for a saturday drive in the nicer $$$ areas looking for defects to their paint job. Take down their addresses & mail them a postcard. Those people know their paint looks like crap but keep pushing it off. If they get your card in the mail they might get reminded of the work that needs done & give you a ring.
So many ways to branch out. Just depends on where you are, what you're after, and how much you want to spend. I'm no pro on this but figured I toss out some ideas. Don't get mad with the sarcasm here either... We're a bunch of contractors who get asked this question every other day by people who usually aren't serious & never post again after getting the decent answers they wanted. They're all good people here once you stick around for a little while. :thumbup:
