Pot hangers like what Ray posted are very commonly stocked by orchid vendors. If there is a show coming up somewhere in a reasonable driving distance you would likely find some there even as you get to peruse the sales tables for more orchids.
perhaps consider sitting the pots in attractive hangnig baskets - I use the curtain rails for my indoor 'chids, they look great with some higher than others, so I have room for more!! S hooks over the rails, attractive lightweight chain or braided cord & smaller S hooks for the baskets to hold onto.
