Affiliate Program / Banner / Ad Management

Hello Programmers, I am looking to setup for a script/software that I can provide to my clients. The overall idea of this will be similiar to an affiliate program/script or something similiar to google adsense, but with a twist. Each of my clients run a webpage/group on a popular Social Networking Site. The mainpage/homepage of each of these webpages/groups is HTML editable. Here is what I am thinking that I would like to do: ADMIN (Me/My Company) - Provide Website/Software for Clients. - Sign Up Form for clients. - Add/Edit/Manamge/Delete Monthly Plans for clients. - Add/Edit/Delete any other important parts of site. CLIENT - Client Sign Up. Basic Sign Up. Name, Address, etc. Email Verification. - Client chooses one of the monthly plans that I have created from the Admin of the site. Ex. $9.95/Month = 25 Ads - Client receives access to their (Client) account. From here clients can add/edit/manage/delete ads. - Client will also need to setup their own montly plans for their own clients. 'Client Customers' - Client will also be provided with HTML to copy and paste into their webpage/group page. - Client will copy and paste this code into their webpage/group. This code will display all banner ads for that clients account. Under the banner ads will be a text link saying 'Advertise Here' or 'Advertise Here for $[login to view URL]'. This will be up to the client to decide. CLIENT CUSTOMERS - A client customer is someone that is interested in advertising on their webpage/group. - All interested client customers will click on the 'Advertise Here' link. If possible I would like to have the HTML area reload with a sign up form. Customer Clients will sign up using the form provided and then also select which of the CLIENTS hosting plan they would like to sign up for. These plans with be the ones that the CLIENT has created previously in their account page. Anyways, basically I am looking for an affiliate program that I can setup, but one that I can charge my CLIENTS to use. My CLIENTS will use this program to manage their own clients, CLIENTS CUSTOMERS. Please provide examples/demos of your Affliate Programs/Softwares. Please also provide your cost for the script and cost for any modifications needed. I am looking for something ASAP!!
