There are 30.6 posts on the market, although they tend to be nice and expensive, or lower end. Do an ebay search on "30.6 seat post" and you can see some options. There aren't any high end jobbies there at the moment (other than Thomson's) though. Regarding your "custom seat sleeve" is concern, please explain further. Is this something that goes inside the seat tube? If so, can't you design it for the ID you want to match the seat post of choice?
