Create a simple/short cartoon animation

We need an animation like this, but with a mouse instead of a chick.

Similar visual style.

If you're interested and can do this for under $500,

please send me:

• Links to similar animations you've done before (DON'T SEND A GENERAL PORTFOLIO WITH LOTS OF IRRELEVANT WORK)
• Your time estimate and price estimate
• How to reach you
• [Bonus] An initial rough sketch of what it would look like

Please DO NOT CONTACT ME

• If your price will be more than $500 for this project
• If you don't have a portfolio with relevant cartoon animations

Some more details about the animation:

• The mouse needs to look cute and (somewhat) young and gender-neutral
• The mouse should look like it's looking for something, but not like it's dancing
• The mouse should (probably) be light gray, but this might change
• The animation needs to be easy to repeat on loop in an app
