Lol it's not the first time I've been asked about something like this. Last time, the client stopped talking to me after I explained that I've never done a video animation before. I mean, I can make animated gifs or sprite sheets+backgrounds for someone else to animate, but that's about it.
Regarding prices, it would vary greatly depending on the complexity of what you would need done. (amount of details, amount of frames, resolution...) I probably would end up charging you by work/hours due to the variety of things needed. And, just like it says on the page, in such cases I charge 15/hour.
Tell me if any of this is ok with you or if you have more doubts and thanks for contacting me. :)
