We could certainly handle the order-taking and download-fulfillment aspect of things for you, but you would be selling all your authors' books yourself and receiving payment in full. It would still be up to you to receive the ebook content from each author, set it up as a product in your E-junkie Seller Admin and upload the ebook file, copy and paste the product's purchase button code into your site. To share revenue, you could use your E-junkie Transaction Log to determine periodic (e.g. annual/quarterly/monthly/weekly) revenue for each author's title(s) and calculate a share you would pay out to them by any means you wish; we have no way of automating this at present.
