Why not cane the seat your self? It's easy and shouldn't take more than an evening to do a seat. I get my supplies from these guys http://www.franksupply.com/ but there are lots of good suppliers out there. Just type "caning supplies" into your browser.
There are lots of folks here (including myself) that can help you out with information if you need.
