No need to have an advertising firm create the same ad 40 times whereas changing the location and entrance fee in the ad is really all the change that is required. Try to involve the record company or import firm that represents the artist you are booking in the tour you are setting up. Explore new markets. Good quality music can be sold anywhere and it will not only help you or the band but will also help the stature of the entire music. Black list list dabblers and inform your counterparts about them.
Dabblers spoil the market, project false expectations and obscure serious business opportunities.
Help other bands to play in your area. Invite or introduce a foreign band you really liked while you played abroad or heard on a CD to a promoter in your own country. A new band will create a new interest with the fans and thus assure the continuation of the festival or club you usually play at. Start acting professional. I have met bands that didn't meet the term they agreed to, showed up late, and looked like bums on stage.
