Just pick up the phone. Many times, just a couple hours of consultation makes a difference. I am frequently out of town promoting for other promoters. If I do not return your email that day, call and leave a message, I will return your call that day. Marketing plans require 1-2 weeks of work.
Research takes time.
A completed inquiry from you is required plus phone and email conversations. Make plans to have your marketing plan 10-20 weeks out, unless a very small event, then an effective marketing plan can be composed in 5 days, as little as 5 weeks out of the show date.
