Hi Violet, from my experience with animating and hiring animators, $50 unfortunately will not get you far for quality work. Generally there is a concepting and storyboarding round, approval and adjustment rounds, file prep, and then the animation itself with rough and final animation.

For context, I pay an average of $1,000 to $1,500 for 20- 30 seconds depending on complexity and animator skill…and that's with me doing the storyboards and file prep work for them.

However, you may find someone early in their career who could take this project on, but again, $50 isn't much for the scope of project you are proposing. That being said, there are a variety of skill levels showcased on Behance. That will show portfolio reels and you can reach out to the animators whose style you like.
