Website Redesign - Script and Database Edit

My site [login to view URL] is currently running Vshare video sharing script, go on to the site to see a live demo. I would like the whole site details and database to be transferred from the Vshare script over to the ClipBucket video sharing script. The main thing that will be needed is to make the existing field tables from the database compatible with the new script so the existing site structure still works including the videos, user details, tags etc. Looking for someone with good SQL skills to redesign the whole site to the new video sharing script
