If he wants to sell based on the rough guideline on assets and memberships you mentioned....
First, how about an independent audit of quoted sales over the last year.. ie at $50K/month.
Second.. a full listing of all content with licensing arrangements or whatever.
Depending on that, smells like it could be anything from, say $150K to possibly $400K or more. Also depends on what it is worth to you.
If actual figures are not available.. tis a totally different story
