Three months ago I bought a Martin 12 stringer and had it sent from Rochester, New York. It was sent by USPS and cost me $120 (about 65 quid) for the postage - this included insurance for the stated value and a track-back facility.

You can imagine I was a bit nervous, but I had absolutely no cause to be. I was given (by email) a shipping number, which alowed me to track where it was. I knew when it left the post office in Rochester, when it arrived at the local airport, when it left the USA, and when and where it arrived in The UK. The time frame was - it was delivered by the seller to his local post office in Rochester on Thursday afternoon, and arrived in the UK on Saturday morning.
It then sat in the Parcel Force Customs in Coventry for 4 days while HM Customs worked out what they could screw me for.
A liberal donation to HM Customs' Christmas party (disguised as VAT, Import Duty, handling charges) left me extremely pissed off, but my guitar arrived at the local Parcel Force Depot in perfect condition.

It was my second experience of USPS & Parcel Force International, and I've no complaints whatsoever.

It's worth adding, though, that my guitar was shipped in a hard shell case and packed by somebody who was used to doing it.

If you get the chance - I'd find a hard shell case for the Taylor if it doesn't already come with one.

Hope this helps
