I don't mean to be negative but I really don't believe that what you are proposing is workable for these reasons.
1) You seem to not be familiar with the US BBQ business marketplace and it's operational characteristics.
2) A partnership (from a legal standpoint) is one of the weakest business arrangements there is and is fraught with pitfalls and problems.
3) Geographical logistics, due to your distance from your proposed marketplace, poses great difficulties in business operations.
4) Your proposed investment is not nearly high enough to make it a viable offer in the US marketplace.
I do not believe you will find a US businessman that will be interested in your proposal due to the items listed above. But I may be wrong. There may be someone out there that is willing to risk their assets. Not me. Sorry
Do I smell SMOKE?????
