You're getting terrible advice here.
Try this.
Hire one of these adult industry lawyers (like this guy
https://adultbizlaw.com/) and have them walk you though what you need. Maybe they will steer you in the right direction in all facets of the adult biz laws/2257/model contracts + where to get the models etc..
There are laws surrounding the production of adult videos. Do not skimp on this.
If you don't have the money to do it right keep working your day job till you do.
Oh and get a good accountant.
