I need an artist/illustrator to convert a photo into vector art /pop art portraits

I want to convert a portrait into vector/layered art, so that it can be easy for me to paint it.
I'll drop a few examples of what I want down below

NOTE-
I'd like to see some of your work before starting to work with you
I'll send you the Pic that I want to convert after having a deal with you

Thank you :)
