I figured I would spend 5-8 hours at each site. It wouldn't take long to set up the node. The remaining time would be spent teaching the owner and staff. Thus, I consider my business to be more of a teaching role than an IT/tech one. Remember, they aren't paying me anything. I have no obligation to them after I leave. I would make myself available for short phone calls if something goes wrong. But there would be no contract and no obligation to do so.

I know there are a lot of options for people, like OpenNode and Voltage. But not many people know about it, unless you're heavily involved in the Bitcoin world already. I'm thinking I can incorporate those services as an option for merchants and I will teach them the pros/cons of each option and let them decide.
