This is not my specialty, however, I have been in your position many many times -- maybe this will help.
If the product is in-tangible, then look for JV partners on the Internet. Try to find an expert that deals with these JV opportunities (like me).
If the product is physical, then look for sales organizations that have networks of sales people across the country. You do the deal with the organization and the independent network of sales people sells your product. It's a sweet setup if you can negotiate a margin that works for everyone.
Hope that helps -
