I'm very interested in writing stories for cash.

You had a line in your message:

I want to see if there would be enough interest if I were to run some contests to write some illustrated stories. I have some sexy content provided by one of our sponsors and they would love to see some smoking hot stories text to go with their content.

By "their content" do you mean their illustrations? It's a bit unclear as to whether you are looking for the story text, the illustrations, or both.

Thanks.
