Why don't you tell us the niche? There are a bazillion products in each niche, so that might help you narrow down who pm's.
Also, why don't you just start a blog and your own autoresponder so you get your own list?
I think your chances are slim to none of someone handing their list over to you.
If you want affiliates, you should list your product with a site that lists affiliate programs.
