Good luck Greg.
Can I suggest that you try to get them on your local TV or Radio. About ten years ago a fellow musician friend found some Tuvan Humi singers busking in Chorlton Manchester. She invited them round to the home local musician famous for his open house to players, where they performed.
I got there at about 12pm and we all swapped Music into the early hours.
The next day she phoned up Granada reports and in the evening they were on the telly. To cut along story short Peter Gabriel heard about them and booked them for WOMAD. They went on to record with lots of people including Frank Zapper.

All the best PP
