Contest writing small contests rules and regulations

We are seeking a skilled individual to craft comprehensive rules and regulations for a small online contest aimed at rebuilding our community following a recent website hack. The contest involves participants identifying objects within a designated image, with a cash prize of $100 awarded to the winner, alongside additional prizes for all entrants. This urgent initiative is set to conclude in January. We require prompt completion, ideally within one or two days. Bids should reflect the modest budget of this project. Your expertise in contest design will be invaluable to our endeavor.
