I can program this idea, but I won't be able to execute it. I need cash for that, which I don't have.
So for anyone interested in this, I can program the site and sell a one-year license to you for a price which is to be discussed(but decided by me), or we could form a partnership and split the money we earn 50:50.
If you decide to buy it, understand that you're buying a one-year license to use the code as is. One week time is granted to point out any faults that arise in regular operation.
If you decide to form a partnership:
I code, you pay and maintain the server. The intellectual property of the site will be yours. Whenever I decide to stop coding, you retain the intellectual rights, on the condition that I will get a bonus of 5% of the total accumulated profit, which you will have to pay. Whenever you decide to stop with this project, I will obtain the rights and you will get a 5% bonus. You will not get the copyrights of the code.
You may, under NO circumstances, share the site code. Doing so will lead to legal proceedings.
You would do better if you released it as copyrighted but not with a time based license. Sell it at a lower cost to more people (it still will not be too many) vs trying to get one or two people who deal with your terms. Charge a nominal (disclosed up front) fee for updates after the first year if you continue developing. The owner should be allowed to modify the code for their own purpose but not re-distribute.
OR...
Put out a group bounty to open source the code.
