Would you mind describing the 3 scripts, and what they will do? Do you have more specific details, because a lot of people may say they can do it, but you haven't given any real details so that applicants can know exactly what they are getting themselves into.
Also, what are the payment terms exactly? You mention income for life, but how and when would the programmer get this money, and how much?
