It would be real nice to have a commercial style forum where you put in a specific piece of code for a banner and a sponsor/member can click it and upload their banner and pay it through the forum. It should all be automated.
Should have options to display by month, impressions, or clicks. You approve the banner and it is then maintained by the sponsor. VB could have a paypal payment gateway as well as some credit card processors. When the banner expires, it would then display some "Click here to advertise with us" message.
In the admin cp, you have all the options for pricing things.
