Barrel Racing Timing Program and Database

I need a windows based software program for barrel racing. App should have a relational database that includes membership information for contestants and also keep track of items purchased such as stalls, RV hookups, camping, hay, etc., and keep track of races entered by contestants. System should be able to create a random draw or running order for the contestants and automatically space riders on multiple horses as far apart as possible. System should keep time and calculate payouts at the conclusion of the race. System should validate whether membership is current and if contestant's birthdate is correct for the class entered. System should be able to work with Quickbooks and have eCommerce functionality for online signups. Budget is small, so please keep that in mind. Thank you!
