Hello, I would like to let the users (let's called them "authors") add items to my store (documents in pdf or images) : - They would categorize it, add the pictures, set the price etc. - Once someone orders this item, i will print it, package it and send it. - I give a % of the final price to the author. - Each author needs to have a dashboard with the recap of his/her sells. Therefore I'm not looking for a multi vendor solution because I'll remain the only seller to package and send the articles. But every customer has to be able to upload new items. Is there any module existing doing something similar ? Thank you
