Developer for digital ecommerce site + android/ios app

Looking for a developer to add functionality to our wordpress ecommerce site. Need to implement a way for our site to automatically create an individual page for specific registered users that people can visit (in our case artists). The artist needs to be able to upload audio and video files to their individual pages through an easy front end dashboard and set prices for their audio files using a paypal plugin. This all has to work within our current theme. The artist pages then need to be viewable to other customers on the site.
