You're looking for vBulletin Service providers ?
We are happy to do maintenance work on vbulletin 3 and vbulletin 4, but we won't touch vBulletin 5. We are however happy to provide migration services to move your vBulletin forum to another platform. See our Xenforo Services
vBulletin to Xenforo Migrations
Did you know we had around 80 vBulletin clients, we have since converted 95% of them to Xenforo successfully, If you would like to Migrate your vBulletin 3, vBulletin 4 or vBulletin 5 forum to Xenforo please get in touch.
vBulletin 3 or 4 Maintenance
While we'd love to be able to solve everyones problems over night, unfortunately some forums need to stay on vbulletin 3 & 4 due to heavy customisation, for those people we are happy to provide monthly support, server management and update support.
vbulletin 3 or 4 Themes
Sorry this is now discontinued, with web standards jumping leaps and bounds over the last 3 or 4 years, it really has put the nail in the coffin for these previous versions. We do not support vBulletin 5 in any shape or form other than migrations away from Vb5.
