How do I find someone in Cuba?

Question

I went to Cuba last summer and REALLY REALLY need to get in touch with someone my group met while out there. All I know is his name, where he was born, his style, and I have a few pictures of him. It would be impossible for me to go back to Cuba for at least another year. Anyone have any clue on what steps I should take to find him?? And how much this service should cost? Thanks!
