There is some ground-floor space in our building, currently used only at night by a sister-in-law: for her bar. I'd like to learn more about coffee in a hands-on manner, while defraying expenses somewhat by selling it by the cup. My sister-in-law will retire eventually, so there's some possibility of turning the space into a proper cafe. My own goal is more to learn more about good coffee with an eye toward importing and mail-order sales in the longer run, as much as possible in a crop-to-cup style.
Given my goals, and my starting point, what would be the easiest path? I.e., what equipment and blends should I consider first, what skills to learn, etc. I've never worked as a barista. I have a lot of respect for how complex a business can be even when it seems simple, and I have other business responsibilities, so I'd like to approach this startup problem as gradually and experimentally as possible.

Well, I did ask for the "easiest path". Would the steps in that path be in that order? The cafe might eventually double as breakfast option for guests at my main business (small hotel -- currently doesn't offer meals). Again: my goal is to learn coffee hands-on, well enough to become a savvy importer and mail-order operator in crop-to-cup style. If the operation gets dumber about coffee later on, that would be OK -- it would have served its main purpose for me.
