Yeah...I'm not thinking that the site mentioned is that good, either. From a design standpoint.
Edit: In fact, after looking at the code, it's really not a very good site - in fact, it's a pretty bad site. (No offense)
If you're looking simply for a developer (to write the code), then any professional should be able to do it.
I don't know why you don't want to hire anyone here...the Advisors, Members of the Month/Year, etc. are all brilliant and fantastic at what they do.
