Curious; how much of a demand is there for a gender fluid/androgynous male model in the Pacific Northwest (and perhaps beyond)? Is this a market that is already tapped out or is there room for one more? ^_^

Best to put out a casting.

I know several non binary & trans people who model.

Many photographers treat them like pokemon, "gotta shoot a trans person" so you do have a niche market.

As with ALL modeling:
You have to have a good portfolio, keep it fresh with rotating images.
Do a lot of networking, BOTH in person & online
Do all the follow up that is required of any freelance job, answer emails promptly, be organized, send thank yous.
Keep GOOD records of your clients. names, emails, locations, likes, dislikes, pay rates...
