I have to agree with Richard...you've put the cart before the horse.

It would be difficult for me to choose a domain name, and then try to fit a product around it. While the domain name may be great, I often spend quite a bit of time researching any ideas I have to see what may or may not be a successful idea...once I have a handful of ideas that I think may be successful, I try to narrow it down to the one that offers the best risk->reward.

In this case, I'd probably sit down and come up with every possible idea I could, and see if you can offer something to the market that isn't already out there. Richard's idea is a good one...but I'd try to come up with more, and then do a comparison of each idea until I narrowed down which one offered the best possible potential outcome.

Don't limit yourself to an ebook...consider trying for audio interviews or video interviews, as this increases the value of your offer. The key factor here would be getting the experts to agree...once you do that, I think you'd have a great product to offer in the end.

Sincerely,

Chris
