I've found a target audience, now what?

I have a background in SEO and found niche that has demand (has high search volumes) and no supply (no adult provider in this niche except for free streaming/amateur ones).

I did some market research and found that the individuals who are in the demographic want to see (I'm not gonna out the niche so I'll use a close example) someone that resembles them fucking someone else that somewhat resembles them but the person is not a family member.

I happen to be a male who resembles the target audience.

I'm creating a few Wordpress sites with articles about the subject and am building links targeting the keywords.

I expect to get traffic within the next month.

What should I do with the traffic? How can I test if the traffic will convert and/or if my assumptions about the traffic are true?

I was thinking of:
* uploading some streaming content about the subject and judge time on site, pages per visit, and metrics like that to determine product-market-fit. I found a lot of amateur content on streaming sites with no copyrights (as far as I can tell). Can I just scrape this and upload it to my site?
* Creating a landing page with amateur photos and videos (from the same source as above) and having a "click here to view price" button to judge interest. Is this a better route?
* If I can't scrape videos, I can do it the more proper way by explaining my offer and having a signup list.

Here are some questions I have:
* If the site's a go, what procedures do I need to have to start filming? Legal paperwork and STI testing advice please.
* I'm gonna be bootstrapping this. How much would good lighting and cameras and tripod cost? I'm trying to figure out a budget.
* Is there an adult crowdsourcing platform where I can ask for funding? I think the demographic would fund a company that provides them with this product.

Thanks!
