Hmm 
Well there are companies that do pretty neat types of coffee....the thing would be figuring out what they would want for you to work there
The other option is figuring out if you want to make your own and sell it

Both would be hard but has potential to be really interesting in the long run

Another would be to learn how to create coffee art...where you make an image with the foam, get really good at it, and work at a really awesome coffee shop that deals with that.
