Unbound Booking is a booking agency run by a friend of mine. She decided to reopen her roster for new clients. If you're in a band or an entertainer, she might be what you need.
But before you drop her an email, I should let you know that his is for professional groups only. If you're new to the business and not sure what you're doing, then keep booking yourself. Build up a great show first.
