To make touring the Cariboo more attractive we have also worked at getting other venues started in nearby towns. You might try the same. Money and other expectations. As host you are responsible for making the performer some money. You may decide to sponsor it yourself, as a party for a set fee, or charge at the door.
Music is worth money so charge accordingly.
Give the performers the door or arrange a percentage split ahead of time to cover costs. We serve coffee and cake. If you are doing one or two concerts a year then you may wish to absorb the costs of phone calls, posters, press releases and mailings. If not, make allowances for this in the door charge and the split. Accomodations and meals are usually provided by the host.
