The best devs don't want to do small projects, as they have enough larger projects worth more money and less hassle. So that is something to consider. Can you put together a larger project? It can also be a matter of how you approach a developer. I wrote a blog post about it recently, because I was tired of getting bad requests. http://www.gnomeontherun.com/index.p...vider&Itemid=7
I find most get-coder websites cater to lower quality developers and lower budget projects. I tried to get jobs on them for a few weeks when I started full time freelancing, and nothing worked out well.
Try to get references from other people who have hired people, talk to other business people you know. I get all my work through references now, and its 30 times better for me and the same would apply to other devs. Stop searching online and start working through your network of contacts. You'll be much happier that way.
Strange how I recommend avoiding the internet in a quest to find a web developer. Its true though, of the requests I get from my website, virtually all of them fall through for one reason for another. However the clients I get through referrals work out at least 75% of the time.
