Advise how to create an unprofitable, but high-quality project
 

I am a full-stack developer, with no adult experience, and I have a slightly strange task ahead of me - I need to create an unprofitable adult project from which I can send traffic to adult dating offers of an ad network, moreover, traffic in quality and quantity is not worse than traffic from an average affiliate. Unprofitable, not in terms of causing yourself as much pain as possible, but in terms of minimizing the time and effort required to maintain the project. As I understand it, the main efforts will have to be focused on finding good purchased traffic.

Please let me know what are the options here, considering:

• The main priority is the quality of incoming traffic, the second priority is the quality of the content, so that it was not a shame to show. That is, you need to control the quality of traffic and content.
• A narrow niche that does not cause excitement for the straight and which will convert well into dating, something like gays or olds.
• Permissible loss in the amount of $300-500 per month

And what if I just send traffic from DSP to ad network offers? What budget is needed to reach this amount of loss in the conversion within an average?
