Chatroom Gateway

I need a chatroom gateway that has an admin control to allow for the placement of advertising. ## Deliverables I am looking to build a site that will be strictly chatrooms. I am in need of a gateway for the chatrooms. The gateway would have the login for the chatroom itself. It will also need to have the ability to have advertising on the frontpage of the gateway and a way to place it there. I dont have time to go in and create the html to do this. This site will almost run on auto pilot. Once in a chatroom, I need to have the ability to have advertising all the way around the chatroom. Example: at the top there will of course be the site header logo but maybe 2/3rds on the right side of the top could be used for advertising. Maybe like a banner scrolling system and then down each side and the footer can all be used for advertising and each section would have a different size. Again this would need to be dont from a control panel so that I dont need to code the page from scratch. I would also like to be able to set the advertising up on a system that when a business is added into a space, once the advertisment is click it will track this information. I also would like to have the advertising set up so it can be done by the person requesting the advertising example: have an advertising login and then have the ability to pick what spot you want, when you want it to run and how long you want it to run for and the ability to pay. Probably use Paypal for this. I can handle all of the graphical work, I just need the shell. This site is in the planning stages now and I am trying to get an idea of how much money I am going to ahve to spend. I am looking at about a 90 day time from to have it up and running once the deal has been made.
