Are Book Authors Good Potential Partners?

[Steven Wade]

The opportunity in partnering with authors is they usually lack a back-end -- they just have a book. There is a lot of potential for massive profits if you broker a back-end for them, and you can make money on both sides of the transaction.

I completely agree with this. Imagine the opportunity you have available with just one book -- i.e. if it's a book on IM, you can connect them with someone who sells IM courses. It otherwise isn't likely to function the same as the type of list you're thinking of.
