Vbulletin modifications - Urgent

I need to create a forum community with a main forum a different indipendents subforums with: - different admins (limited to their subforums) - possibility for the "sub-admin" to manage users for his subforum - possibility to edit skins, smilies, levels, images and so on for his subforum - possibility to host the subforum on a subdomain (same server) - separated mailing lists and statistics information for every subforum Every subforum must be totally indipendent and evey admin must have the possibility to manage his subforum. The main forum must contain the information of all the subforums and also the possibility to manage them all. Some detail could be added later to the project (limitations for the subforum admin for example), but the project is almost defined. You must provide documentation of the work done (a text file containing: modified files, code before, code after, brief expaination of the modification) I will escrow payment through GAF when the bid is accepted and release it after the job is completed and the code verified. Feel free to contact me through PM if you need further details. Thank you
