Looking for indie authors with finished titles (wattpad/tumblr/AO3/etc)

Hi! I'm a talent scout for a digital publishing company. I'm looking for authors with finished pieces to publish under non-exclusive agreements (this means that you will retain all the rights to your work). The revenue comes from a royalty-splitting system, so if the book is popular in our platforms, the revenue can reach a high amount (per month).
The pieces will be published in a serialized format, so the length is an important requirement.
