I think GFY is one good way. Just post a "About to do biz with..." thread and ask others for their past experience.
I personally was taken for a total of $275 (2 TGP site designs in 2003) from 2 people who are now long gone. So now, because of these 2 individuals, others have lost out of any income from me unless they are willing to take payment upon delivery of product... $275 is not a lot of money but it's the princable.
I never called out anyone either on GFY or other boards. I have a firm belief in Carma...
