Here's a short, 10 second animation I whipped up in about a week. (If I am given more time, the end result will have a higher framerate and look more refined, of course. This is here mainly to show that I can produce passable results on a tight schedule.): https://youtu.be/rTHDmqv6rns

Whether I will work for free or not depends on the scope of your project and how interested I am in it, as well as how much work I will have to do. Chances are, if you are a smaller project, I will not ask for money. If the project is commercial, I would prefer to get compensation, however, I'm open for negotiations.
If you are interested, please PM me, and we will discuss the pricing, as well as your preferred method of communication.
