You need to give more info, 35% of your buiness is meaningless uless we know what your business is. Also, how do we know this is fair unless we know your contribution?
Okay,
my contribution is coming up with the whole business idea in the first place. Without the idea there are no winnings.
Secondly I have the server.
Third I will take care of calculations/optimizations - just not the implementation.
More information please.
More info is available if you sign a NDA with my organization.
As a general oppinion: this is not a job - this is a venture capital: you have a risk factor in it. It might or might not work, but only the few that are willing to take the chance can get something ("you can only win the lottery if you play it")
