Hi Lydia! We have used several sources for our custom crating needs. You will need to work out the measurements & any specific packing design needs you want met. Make up a list of local carpenters who do custom work, present them with your needs & request a bid & recommendations (viewing a sample of their work is useful). Or, perhaps your local shipping agent can help. If we tell them what we want, the lowest cost & best built crates we have obtained have been put together by a local freight company with whom we do business. "Museum Registration Methods" published by AAM has a good section on crate building that might be useful to you. Good Luck, Sue Thompson Sr. Registrar MOA/BYU
