Need advice about JV

Hi guys, i get offer from my friend. He's good in making e-book.I ever buy him e-book and it is great, using simple word and the content is original. He ever reach $60/day for only selling that e-book. The e-book is about MRR business.

A week ago, he request me to make idea about next e-book. And he's the one who write it. So, i give idea, he's writing it. I never have a Joint Venture experience before and i'm quite doubt about this offer. Is he honest/no? What should i prepare for this joint venture? Even i'm JV with my friend, but we live on different city and scam probability still excist. I don't want to get scammed.

And do you think giving idea is more important so i should request to receive more big % of revenue sharing?


Note : Sorry if my thread is wrong area, please move it

Just for an idea (unless it is a KILLER one) I don't think you should take anything.

If he is doing all the hard work, why should you ask for any share?

Are you doing any of the actual writing, promoting, selling, or anything? Because I think then you should have some cash. Ideas aren't really worth much :/

Not fully just an idea, but i'm also manage the marketing proccess. He said, he is lazy in manage marketing, and have no idea about e-book, so he is request me to do it.
About idea, don't you think it's important? Since content source is start from just an idea. CMIIW :D
