Have you thought of getting a partner to split the work?
I did try that before but it unfortunately never worked out long term for a variety of reasons. I brought on 3 people in the past but it's rather difficult to split the work up because about 75% is focused on creating the renders in Daz. Someone who could take that on is already capable of creating their own VN, so why would they do all that work for a revenue split when they could take home all the revenue on their own project?
This leaves the remaining 25% of the workload for writing, coding, promotion, etc. It's extremely uncommon to find people who have a skillset in more than one area so that means they can only do a smaller portion of that remaining 25% (writing only, coding only, etc.). It's already hard enough finding one person to work with, finding multiple fitting people is even more so.
For me, I would have to find someone who is damn near a perfect match for the exact areas I need help in. The right candidate would also need to have a compatible schedule and be willing to work for no or low pay in the hopes that the project will take off.
All that to say splitting the work is complicated.
