Hello,
I cannot help you on your code, but last time when I write a service
that offering WCF restful service, I use WCF Web
API(http://wcf.codeplex.com/wikipage?title=WCF%20Web%20API%20is%20now
%20ASP.NET%20Web%20API),
it's really easy to use, because you don't have to write code to
compose request and parse response, all you need to do is focusing on
your business rule. Another awesome point is there's a test tool
integrated in the API.
If you just on the start point of your project, I strongly recommend
you give it a try.
