You should talk to the owner of the product and see if you can purchase resell rights to it or maybe lease it and give her a percentage of what you sell. If she's having financial problems, it wouldn't make sense for her not to negotiate with you.

If she turns you down, then I think it would be a waste of your time to continue to market this product. There's not very much time between now and August 10th. You might get a few sales but you will have to decide whether it's worth your time or not.
