Create a Wiki for law (i.e. a clone of wikipedia.org)

I need someone to create a wiki platform for law related topics. Articles and comments should be easily added. I anticipate that there should be two, if not three login options. The first for the general public/lawyers to add information. The second for admin to review and disallow posts. The third should be for advertisers to be able to pay for and pick advertising programs. Advertising is to be present in the top of the screen and in the right hand corner. Changes to the advertising should be allowed by admin. I anticipate that the coding should be easily transferable to other areas if we choose to move into those areas, such as real estate, or insurance, or banking. Further details about the project to be discussed with the coder.
