Business ideas need talent in software development + more

I need people experienced in business development, website development, marketing, sales, and more to help develop business ideas into sustainable businesses in areas including waste management, agriculture, and energy. I do not have the risk capital to pay people upfront, I can only pay once the contractor generates revenue for the business, and once one does that he or she will be paid fairly. Experience in the business areas / industry sectors mentioned above is helpful, but maybe not essential. The businesses are all in the very early stage of being just ideas, and I want to develop them into sustainable businesses. The budget of the project is relative, not fixed. The budget is relative to the ability of candidates to turn the business ideas into sustainable businesses, and generating capital growth. The timeframe of a project can be as short as 5 minutes, or as long as the business runs for--again it is relative to achieving a sustainable business. Please say "sustainable business development" in your submission to show that you have read this post. Candidates don't need to have knowledge or experience in all of the desired areas that help is sought, but the more knowledge and experience candidates have, the better. The agriculture business is about using underutilized land to grow value producing crops like food and oil, and returning value to landowners. I have several business ideas in the energy sector, but they all have the common goal of maximising value to end-users of energy. The waste management business is about making valuable discarded materials simpler to find. I want to develop an app that maximises value for food shopping. I need help from an experienced software developer for this. Proof of past work is required. I have ideas of how to monetize all of the business ideas that I think are sound.
