Searching for Animation Vendor

Now, I'm making some MOCAP animations, but I need an Animation Vendor to sell my animation.

Requirements
1. I want embed many animations (5 animations more).
2. vendor has arrows to change animations.
3. small prims.
4. vendor permits modify.
5. vendor hand over a Notecard to customers.
6. vendor sends messages to me if animations are sold.
7. low price!

I searched on google, 2 vendors was hit. "1 prim Animation Vendor" & "Animation Vendor V2.1.0".

I understood via trial and error, vendor script is difficult... and I want to change texture of its. There are many problems to solve...
