Sprite sheet help please

Sprite sheet help please

Hi, I am in need of an artist to create some sprite sheets for my game. I have the original images, as well as a couple sprite sheets that were already made from previous artists, but my idea has kind of changed for the game and they are not what I am looking for.

The game is called Neighborhood Troubles and it is a 2D platformer. The art style is considered as "Chibi", where the characters have large heads and smaller bodies. At the moment, the game is not open source and I am making it as a project for one of my college classes.

I will attach the old sprite sheets and the other characters I would like sprite sheets for.

I am looking to have all three sprites to look like they are walking. Would prefer somewhere between 8 to 16 sprites in the sprite sheet for each one and possibly have them as a 32 x 32 resolution (not sure what is best for resolution, I am using Unity 3D to create the game).

For the main character sprite, not only am I looking for him to walk, but I would also like some sprites of him attacking, preferably him punching or possibly attacking with a crow bar. Not sure how many sprites it would take to be able to do this, but if it can be done is a small amount, that would be preferred.

If someone could help me out, I would really appreciate it. Thank you in advance as well to who helps me out.
