I'm envisioning my future coffee house, and I'm thinking about providing a gentle variety of live music. I'll be a first-time startup, so cost is always a concern, but I'm hoping to lean on the experience of people here in terms of how much extra business I can expect from it. For those of you that have provided live music (single event or all day), what type of performer(s) did you employ, and what sort of results did you get? What sort of pay is typical for such performers (assuming they're not bad but not the best of the best either). Any information or advice is appreciated. Thanks.
