Now how in heck do I go about determing what to charge them?
Is $100 a month too little? Too much? Just about right?
Also will Adsense allow me to have a page sponsor for the same page its ads are appearing on?
If you can't then just adsense the page or site, and no - i don't believe that you can use any other form of advertising system in conjuction with adsense, if they catch you - they will drop your account!
Why not continue with adsense, and offer the space for advertising and see if you can get customers, then drop the adsense of the page, once you have paid up customers - usually the potential advertisers are going to be fully aware of banner based advertising, hence make sure what they are getting is a deal - content targetting and traffic wise.
This seems to work well for the UK site.
You really should read some of the threads here at webmasterworld [google.com] and understand the risks before you jump in.
