Set up a back end system on Wix

Picture Airbnb for a moment. They have a system built where certain people go to sign up and they post their properties on, and the set of people looking to rent the property use the same system to book the listings. I need to integrate a system that works the same way for people to list a certain service/product and for buyers to obtain said product. Payout will be based on the difficulty to integrate these systems into a Wix website. Please reach out with your quote for labor, plus whatever the cost is for the service that will be integrated.

Thank you.
