Create a profile unassociated with you, change the cities as you travel if you do. Use it exclusively for advertising for what you want.
Be picky, ask a lot of questions before you reveal who you are. before a face reveal (because they will see your face eventually) send body shots, cover tattoos.
Keep yourself safe if you want anonymity.
Also,
If you're going to take the anon advertisement route make sure you fill out an in depth profile about you and the Mrs. You don't want liars or flakes, so make sure you interview people. It's better to say no thanks to 100 dudes that are one offs to find the one that will keep hush and be exactly what you need.
