I'm glad you enjoyed the sales letter. I wrote 95% of it and then ran out of time so I had a copywriter finish it off.
Regarding your quest for honest JV's, I'd be more than happy to help you out. One thing that my co-author and I do bi-weekly for our subscribers is interview experts in different fields. We've found this very successful for selling other people's products and at the same time establishing the person as an expert and giving our list valuable information.
I'll PM you with more info on this, but I was wondering if it's something you'd be interested in.
