Here's the conversation I've had several times now:

MY WORK: "We need a rendered walk cycle of (insert some dude). How long do you need?"

ME: "About a day or two to come up with a character and get it ready for animation, looking right, decent shaders, then a few hours per animation cycle for whatever is needed".

MY WORK: "Can't we just buy a character, and you can start animating straight away? We need some animation today. Here are three that I like - (link, link, and link)."

ME: "Those characters on Turbosquid are not in Maya format, I can convert them but I'd still have to apply a rig to them, redo the skin weights, and possibly fix other issues."

MY WORK: "Well can't you find a Maya format character for us to buy?"

ME: "I'll look into it."

....

And so I look into it.

And I find nothing.
