Plugin for my sellers to make money

I was wondering does anyone know of a Plugin I can use on my site for my customers I have a site where they can upload there designs and we make them items and send them out now I’am wanted to apply a plugin that will let those same customers make money on our site with there own designs if others buy it for example….

I have a hat I designed on the site and five others customers see it and now they want to buy it after I sell them I would make a percentage for each item I sell..

if anyone knows of a thing I would appreciate it very much Thanks
