I imagine that the reason there is no one selling those kinds of instruments localy to you is because it is a specialised area of the music trade. Try talking to the nearest nearest outlet to you that DOES trade in these instruments and see if you could take a sample of their stock and sell it for them.....that alows you to build up your own expertese and contacts without serious risk but still offer a service to your local customers. And your "partner" retailer will benefit from having access to a market that currently they can not reach. Good Luck
