How to launch a webcam platform with minimal investment

I have created a platform for one-on-one video calls. Please advise on how to launch everything legally with minimal costs:
1. How to set up the system so that I can pay the models who work.
2. How to make it as convenient as possible for clients to top up their accounts.
3. Payment systems.

I don’t really understand where to start to launch as quickly as possible with minimal investment.
