Nothing wrong with doing things your way as such, Ebbie.

However, as I suggested earlier (And more tactfully than GSS), you get what you pay for(or don't)to a certain extent.

Yes, there is no reason why you shouldn't get some good quality performers from time to time. Good "up and coming" acts may wish to find a platform to make themselves better known while you'll also get good local performers or visiting musicians who are content just to enjoy the experience and will support your concept.

However, I don't think this can always be guaranteed and it's probably inevitable that you'll have to take the rough with the smooth from time to time.
