Michelle,
You might try posing this question to Catalyst and the marketing pros over at
Affiliate Marketing - she's a gem and has a plethora of information and resources about these type sites and subjects.
In the interim:
Have you considered marketing it as a business for sale and not an Internet business?
Check out your local SBA (Small Business Admin) for more resources and ideas too!
Good luck - let me know how it goes - this is an interesting topic I've not seen a lot of good answers for; it'll be interesting to see how it pans out for you.
