Coffee Coasters

Life's been a little crazy around here lately, so I've been slackin on my posts here, but I need help from my fellow dribbblers:

I'd like to make some coasters, perhaps out of cork, maybe something else? Maybe a series of different beverages, maybe just "coffee" for now. Can any of you recommend a business to facilitate this whether it be die cut or laser cut or however the hell a project like this would be properly executed?

Thanks!!
