Add-on [Paid] Backend integration for fully finished XenForo based site

As the title says we are needing someone to do the backend integration for our new frontend.
The site is completely Xenforo based. We have all the backend done with PHP, but cannot use it with Xenforo.
Site link:

Need to pull and display:
  • Information from our database for the player counters
  • The latest post title from our Announcement section
  • 5 most recent threads from our forums (Needs to be limited to certain sections)
  • The latest tweet from our Twitter
We have an example PHP class and a live demo of what we'd like if needed.

If you are interested PM me or post below.
If you are going to need site access or database access you will be signing a NDA.
