Talk to an immigration attorney first.

An F1 visa has significant limitations regarding work.

Violation of its terms could get you deported.

Deportation from the US often comes with a long term ban on entry.

If it doesn’t seem reasonable to pay an attorney for $16/user/month, that is an indication that the potential business is not actually viable…legal fees are an ordinary operating expense for a viable business.

Keep in mind that what you are considering leaves a clear paper trail should ICE decide to investigate.

Good luck.
