Draw some happy faces

Hi
This is a really quick job for someone with drawing skills. I have attached a drawing / graphic. It's not mine but I would like a series of 20 happy faces drawn 10 male 10 female / mixed race in this style please. In colour.

You must provide evidence of similar work.

The drawing need be on a pure white background and need to be provided as png at 300 dpi. You don't need to add any wording its just the faces I want.

That's it!

Thanks Any questions?
