It sounds like a great product.

Well, a good starting place would be to recruit some affiliates through here & also MunchEye. You could also try having an affiliate contest with lump size cash prizes for high performers.

With regards to searching for possible JV partners, what i like to do is type this into the search engine "your niche/relevant topic" + JV leader board.

YOu should then get some sites where you have other product leader boards where the top potential JV partners can be found.

Once found, contact them & ask for if they would like to partner up with you for the launch. Make your emails concise & offer a generous incentive for them to say 'yes'!

Good luck
Az
