TF2 Taunt Animation Idea (3 seconds)

Hi, I just recently started playing TeamFortress2. Great game.
Apparently, you can make items and taunts and stuff to submit to the game and maybe they’ll be accepted( you will get royalties on whatever u design, from the shop).

I have an idea about a couple of cool/funny middle finger taunts but i have no experience or confidence in animating characters. Example:

Pm me if you are interested in making it( you can keep whatever money it might bring in).
Ill send you a video of what it is supposed to look like.
All files with characters and whatever you might need are downloadable.
