Create a collage

I am looking for someone to create a personal collage for me using approx 200 hotel key cards I’ve collected from 15+ years of traveling. This would entail organizing the plastic cards in a way that creates an interesting piece of artwork. I have all the key cards that I want to be included in the collage—they will need to be arranged artfully and in a visually-pleasing way. I’m giving the artist almost full creative license, but I would like to have final input on the design before it is finalized. The end result should be a visually-striking collage that I can proudly display.
