!! Help an Annoyed Artist out? (Art help wanted)

I've been working on a decal for my car, my green baby, for the past couple weeks. I have most of it done except one stupid leg.

I've drafted and re-drafted this thing several times and just can't get it to look right. That background leg has always been an issue for me which is why I tend to hide it in my other works, but I need it stretched out this time. -__-

SO, I'm turning to my fellow artists here on Wolvden to help me settle this thing before I yank my hair out.

The only draft I've gotten remotely close.

Hopefully that's enough to convey the pose/position I need that back leg in. Here's my car and the space I have to work with as well, for reference. I've edited in what I have so far - I'm very pleased with how the foreground leg turned out. Just need the other one.

If you're good at anatomy and interested in helping, please let me know your ideal price (I can offer GC and a tiny bit of SC, or U$D if it's not too much.) 

I can send the PSD file to work with as well, or a high-res JPG.

Please and thank you. Fingers crossed. :D

I tried XD Feel free to trace or modify it!

That’s great! Almost exactly what I was envisioning. How much should I send you?
