335898 Just an approxiamate cost

Hi I appreciate your time to answer an approx cost ? I want to build a bux type of system that serves two types of login customers. Instead of PTC I want the first customers to: submit questions, rate questions (for statistical analysis of the qs) Have a levelled system according to the work they have done in the system sweepstakes etc But all in a cash per action system like a ptc that they can cashout from The second customers: sweepstakes login to answer level and subject specific pretested questions. Have a level system according to their correct answers also enabling them to cashout from their gains. What would be a likely estimate for this project?
