Not sure if I am posting in the right place so forgive me if not. Is there a software out there or website template that will allow me to sell or more importantly showcase my items and have a representative sign up where the rep signs up and pays a fee and gets a pre-made website (maybe template choice/customization)
under my domain ( ex: ) and they can have signups under their account and make a percentage from their sales?

I am looking for a template package or software. Any help or proper terms for what I am looking for is greatly appreciated!
