Freelancers Please Read This...

I have always had this project that I wanted to persue and as some of you might have already seen a post or two for it. The problem I have is I do not any funds to pay the freelancer upfront until I have used the program and generated revenue. Now I have confidence in this and I will pay the chosen freelancer a negotiable amount. Trust is not an issue because we will discuss that. If there is a good freelancer willing to work arround this for me I would love to hear from you.
