Why not us? I have administrated and created this one : [login to view URL] Vbulletin with a socialise theme, we can merge to a VB5 if you want to however the VB4 is better for your forum
With your forum, not only the design matter however i can handle it and you'll get with in a couple of hours, then we'll handle the anti-spam and DDos attack to make it securily.
Contact me and we'll handle it
