With a view to protecting your interests, I would respectfully like to suggest that you phone instead of email.  In conversation, we could most concisely and comprehensively discuss your requirements and ideas for the music element of your event or concert, and then, what I can offer to accommodate them.

In short, it has been my experience that a phone conversation is likely to be much more helpful to you (and in the long run, more time-efficient) than just emailing a request for information and a quote.

In any case, I would very much look forward to hear from and serve you.
