Hey there,
My name is Rafael Benard and I'm a vBulletin expert since 8 years.
I've coded hundreds of vBulletin skins and lots of custom forum plugins for sucessfull communities, not only at the development side but also from a SEO perspective too, and I would love to do the same for you!
I don't want to bore you with lots of links, but I'm glad you pointed to the supercell forums as a reference, since I was the one who participated in their coding (the firm hired me as consultant) so I know how to do this and how to do it right and fast.
You'll not only get my help with the setup of vBulletin at AWS (which a lot of people here doesn't even have any clue on how to perform) but I'll also help you to setup the forum lists and categories, the forum plugins and modifications that I recommend for a gaming community forums, the antispam and antihack trap so you don't have bad surprises and also, the Coppa (that's how they call it) protection against child registering at the forums.
Further note, the skin will be SEO optimized, lightweight, and also, I'll install a base skin for the mobile devices, but if you also want the mobile skin customized the price would slightly increase. I can also install the mobile apps for you (Tapatalk) but if you need the vB inbuilt apps, we'll discuss it's price too.
PRICES ARE NEGOTIABLE. And, turnaround is 7 days, could be 3 but would need to rethink the price as I'll have to drop other projects to make it up.
Looking forward for you.
Rafael
