howya I know it may seem a wee bit in the wrong direction, but myself and essjay from this site used
http://www.2wglobal.com (over in southhampton)
to ship our bikes over to New Jersey in 2008...
They stop in Halifax on the way down to New Jersey... no crate needed which was the big thing for us.. and we packed our bikes out with all our camping crap
It took about 7 days.... if memory serves it was about 575 pounds..
they only reason they had to charge us the full 575, was that we took up a full car space on the ferry (its roll on , roll off)
they said they were bringing in bike spaces soon.. so it might be cheaper..
we rode over, and ryanair back from the local airport...
as I said .. might not suit you. but for the time and the money (plus no crate) it was great value for us...
