Hello everyone! I need your help

I'm a newbie in coffee vending business.. I need your comments, ideas and suggestions to help improve sales. Actually the coffee machine that I choose is pretty unique and offers a variety of “cappuccino” flavors (for what it is intended, that are of the likes of starbucks

). But it is intended to sit next to the coffee pot of a great tasting coffee for those that like alternatives to coffee. Are there other things that I missed?
If you have more ideas please help me!!!
Thank you so much
