There are a few local lads that specialise in bringing bikes back from England. Probably work out cheaper in the long run?

I have used him 3 times and each time it has been faultless. He is very busy but will take care of your new purchase.
And if you do decide to get a trailer, any trailer would do. I'd rather have a box trailer so it can parked up without prying eyes seeing the bike.
@PeteMoore might be able to point you in the direction of his mate Will. He was going to bring a bike home for me, very approachable, decent price and it would be well looked after.
Should have said Will is over at the minute collecting bikes etc. Could save you the hassleGot a trailer and going over to England on Thursday to collect it. The boat over is free so may as well.
