Caricatures for wedding

I'm looking for a talented artist to create caricatures of my wedding guests for a special event. The style should be realistic, with full body illustrations. I need more than 5 of them, so the artist has to be ready to commit and draw a fair amount of caricatures. I can provide photographs of the individuals for reference, or the artist could work from descriptions if preferred. I would like a few rough sketches of the finished work prior to any payment.
