Need some direction

I'm looking to do some costuming this year, first time, and I'm not sure how to approach it. It's simple enough for the most part I'll be using liquid latex but now I need to track down someone who can do me a tail. Sounds simple right? Well... not in this case unfortunatly and I can't seem to get any response. I'm looking for an orca tail, the problem lies in that I don't want it thin and fuzzy. Rather, I want one that's nice and girthy and tapered like a real one and covered in vinal or leather. There's that and of all the face prosthetics I see out there none are very appealing in this application. So... suggestions anyone?
