Need help getting a prosthetic stp

I'll get straight to the point.
I'm in need of a transgender prosthetic to help me pass easier in public restrooms and to ease my dysphoria. 

Due to my anatomy being the way it is and having tried other cheaper options that didn't work, I came across a prosthetic made by another transmale that would fit perfectly with what I have.
My issue is I've got a mountain of bills to pay and this prosthetic has been on my wishlist for well over a year. Due to the increasing issues with transpersons and bathrooms in public, having this would mean a lot more for my safety and also help with managing my dysphoria.

If you could offer anything towards this I'd be eternally grateful.
