I need a caricature artist for 5 people

I am leaving my company and would like caricatures for 5 people to give to them when I leave, that shows their character in a funny way. I will give photo of each person with some background, and some of their strong characteristics that can be emphasized in the sketch. Can all be electronic. But must be printable

I do not yet have photos, I would like to understand the approximate cost for something like this before pursuiing any further.
