well what do you need? if you're just looking for a php/mysql content management system to install, you shouldn't have any trouble finding one. but if you're just looking for bits and pieces of free code to use to construct a site, then just try googling it, or maybe searching on the
hotscripts site. unless you're looking for scripts that perform really obscure tasks, i'm sure you'll find what you need.
if yer looking for somebody to write some code, i would consider lending a hand. but i don't have tonnes of time to devote, so i wouldn't do it if it was a really big job.
