Life Time Commisions - Free Website for Professionals

First, we're not sure about the budget, so let us know how much would you charge per client. We want to offer professionals and small business owners a free website. The website is $0 design and development costs. The websites are very good looking and web 2.0 style. The catch is that the client to receive his free site ($1500 value) will need to signup for our hosting and maintenance fees package $19.90/month (fully fledged web hosting with cpanel + our maintenance services like security, server and web site administration, etc, etc). We offer to the seller life time comissions. So 20% of the monthly fee payed by the client will be payed to the seller for as long as the client stays with us (web hosting clients rarely change hosting company if everything is ok). Please let us know your ideas and more or less how many clients can you get a week.
