You're probably going to want to find a local commissioner for this. I just made two bunny suits for friends, using the duct tape and plastic wrap pattern method, and even after all that we had to do a fair number of adjustments to get it to fit perfectly. It's really, really hard to do without the actual body there.
I notice you're in Springfield, VA, which is about a two hour drive from me in Delaware. If that's not too far for you to want to drive sometime, I could definitely help you. My gallery is dye-another-day.deviantart.com, though I don't have any pictures of the suits I made for a friend yet. Let me know if you're still interested, and we can talk price.
