Have you tried Consumer Reports? They've got everything from olive oil to computers to tv's. I don't make a move without them!!!

Restaurant supply store.

Go to ebay and get familiar with coffee makers... read the descriptions to see what they do.. I personally like the bunn machines and ebay has one on there right now.. a smaller commercial model I think.

SEW= check it out.

Easiest way is to look in your local phone book for a restaurant supply store. They carry commercial models and can explain the benefits and drawbacks of each. I would recommend one that brews into a thermal pump carafe. Get a few carafes and you can brew plenty... or different types.

Any Food Service Distributors where you live ?
US Food Service
Sysco
Gordon Food Service

Buy a simple pour over, new or used, to get it free the distributor will need you to buy at least 7.5 lb of coffee per week

you said good cup of coffee, this is the key to selling coffee, there are only pennies different per pot when you are selling the very best or the worst, good coffee will keep them coming back, you will need a decaf also, buy the best they have, buy the fractional pack, have them sample you on the different sizes-.9 oz/1 oz.1.5 oz/1.75 oz/2 oz. Only open the bags when you are ready to make coffee, ground coffee exposed to the air has a 20 minute shelf life.

Good Luck
