What're you looking to spend? Are you looking at having a "from scratch" build or using some sort of 3rd party system?
I know several of us do web development, but I don't really muck with 3rd party systems... Then again, I'm not exactly cheap either (depending on what all needs done)...
Although I do have a firm grasp of php & mysql, xhtml & css, web validity, and have numerous examples (UGN Security
and The GoNix Initiative
to name a few) :P.
