I am in need of an artist to pose nude for my exclusive album... how can I approach a model to do so?

Maybe I'm completely wrong, but looking at your other post, I would assume that you were a voyeur. So seriously, go to therapy.

Unless you are a recognized pro operating a viable studio no female in her right mind would even consider your request.

You can advertise for nude models and you might get someone who has not got any more clues than you do to professionalism.

Exclusive album? Gimme a break.

Of course real models will expect a real studio, and they are not cheap.
Back in my younger days, I was in the fashion industry and we hired professional models to do nighware at shows. This was in the early 80's and they were getting 100 to 150 dollars a hour then

Of course you can check out massage parlors and newspaper adds for spas and I am sure you can hire about anything you want.

But then please don't try and make your personal perversions sound like art and professional photography.
