Sending to Jersey

Jersey is one of those conundrum countries.
I have just had my first order to Jersey, and, although it is classed as UK I need a customs form.

I have also discovered that My Hermes don’t deliver to Jersey.
And my item is too big to be sent as a small parcel with Royal Mail, so I will be taking a hit on postage.

I was wondering if anyone selling bulky/heavy items has set up exclusions for certain places, I. Jersey, which come under UK postage prices, but will obviously cost more for sellers - like me - who would normally use a courier.
