I have a couple of hair-stylist friends who've been dying for this kind of service - there's almost a kind of lock-in with the salon that they work out of, where changing causes them a great deal of frustration. Having a direct line to the service provider would save them (and their clients) a ton of hassle, and also even up the power-balance. Everyone wins!

I'm personally a little bit jealous about Opez though - building a product by establishing relationships to the best bartenders, servers, etc.? Must be awesome :)
