Customized Search Engine

This is a fairly simple request. I'm looking for someone to build an attractive looking search engine for our social network community. I'd like to be able to just pull up in search as a priority, all tags on the network. The tags are located in different folders depending on what kind they are - video/forum/blog/resources/page etc... As an example: [login to view URL] where animation is the tag. or [login to view URL] where tools is the tag. So basically a macro needs to be created to pull up the tags to search across these urls. After the tags have been searched and called up and displayed/prioritized, then any other content can be listed. Thanks for your attention and I hope someone with good search engine building skills will apply and build something nice for our teaching community. thanks, David
