Create Small PNG Assets

I am looking for a Photoshop artist/illustrator who can take some of our PNG artwork and create multiple colors and textures out of it. We would like your cost for 10 assets. Then, we can keep hiring you over and over for 10 assets.

We understand that once an asset is ready in Photoshop, you can change colors quickly. Please don’t over bid.

The idea is to take things that we have created and use your skills to provide us with different colors and styles. These assets are small.
