Assist me with Bulk Marketing

I would like to write a presentation letter in regard to offer my Salsa Band in different companies, organizations as an entertainment Band. Also I would like to reach other segment of customers to be present in public events as Melbourne cup or Festivals around Melbourne. This letter would be attach with a presentation CD. It'd show the band, history, musicians and the performance. My idea is sale a show, with a couple of dancers to teach people salsa steps, how to dance. This couple and the band will make the party sparkling and motivated the people to enjoy.
