I purchased a vBulletin addon with the intent to modify it to work for my own custom forum software (which is mostly made by me); I have their permission to modify their code btw.
The addon can be found here:

Maybe the easiest way to go about this is I give you the variables and DB info my site uses and you modify the software so that it works with it. I would also like the scheme to match my sites scheme (I would provide you with the info necessary to do this).
