The prices look reasonable to me. Their certified organic offerings are in line with what we will be selling our organic/kosher beans for. Not sure of their quality, though. There is no indication of specific estate or coop producing the beans. You would need to get the beans in front of your person with knowledge of the industry. Hiring a barista/shop manager would help with these issues. That person would probably have a working knowledge of the local roasters products.
Keep in mind that coffee beans will be only a small part of your overhead. If you use the estimate of 8 grams of coffee beans for each cup, that comes to 56 cups/lb. At $2/cup, that leads to $112 in revenue for a single pound. That means a 5 lb. bag of beans will bring in around $560. That corresponds to cash outlay of $35 to $45 with prices between $7 and $9/lb.
