I'd contact the manufacturers and see what you can get. Smaller indie brands dont always get the sales, but I frequented the shops that sold some of the rarer brands back in Seattle. Even if I didnt buy a pair of skis from that shop, I supported them by getting mounts done there, buying gloves, etc. Having rare brands can set apart your store from the competition for sure, but I dont know how well you could realistically expect them to sell compared to tried and true brands. You'll get respect from the people really into skiing, but might not get interest from the other 75% of your customers.
