I'm curious because i have a buseniss plan here that basically guarantees a 20% return on each $10 invested on let's say a minimal total budget of atleast 50k. I'm wondering since alot of capitalists are on this forum so is that an attractive offer if you consider investing in a start-up?

If not what is it that you are looking for in an investment and what can i do to make it more desirable when i actually decide to go for it?
