Mambo Modification

I need a modification to Mambo done tonight! need multi-site ability added, users must be seperate by "web site" what we are doing is using a mambo install to demo our sites, we are running short and need the mod done tonight I have seen this mod done before, but cannot find the module, need someone with the module and to install / configure it. also need a admin side mod, need a admin module to configure what is available to the users and super users. must be simple and clean, if someone has this available I would like to see a demo. the goal is to make a very "dumbed down" verson for the site admin, while allowing us a user that is not able to be changed by the site admin allowing us the ability to the FULL admin panel.
