Let me give you a detailed explanation, to see what I have in mind.
I was thinking on making a collection of sexy or R18 pics of your girls and mine and turning it into a small booklet, as I did with the Endless Summer Artbook It wouldn't be a massive commitment (20-30 pics would do), and it would be something that could be dealt with in a long time basis, I have no deadline since there is no coordination to be done.
I can provide ideas, sketches, constructive criticism and I would handle the editing process.
The gist of it is that, once it is done, and since the pics are yours, you would be able to sell the artbook for your own profit. I just want the credit and a digital copy for myself.
Please give it a thought and let me know what you think.
