No, I usually pick the job from my own calls/leads. If I get a call for a small, decent job, such as the one I posted about above, and I think I could capitalize on the client/business, then I offer my services for free if they will write up and submit a press release in the local papers.
The project should be a high-profile or well known orginization. Like a children's hosp., Ronald McDonald house, local shelter for battered women, etc. etc. Habitat for humanity wouldn't fit the bill because it is chock full of people donating time, you are a little fish in a big sea on those projects. Pick one that will make you alone shine.
I use my SW rep and persuade them to donate wallpaper, primer, paste, etc. They usually have no problem with it. I always make sure they are credited for the materials in any marketing done.
I use a little proposal that states I will provide my services for free, with all regular warrantees, if THEY submit a press release to 2 newspapers within 30 days of the project. And these big organizations with a PR staff will write up something 10 times better than I could. These look great in a sales presentation or portfolio.
I have gotten many referrals from these jobs, plus it makes me feel all warm and fuzzy inside. :cheesygri
