I used PetAir UK to relocate my Jack Russell Terrier from London. I went for the gold service - which means I do not worry about anything from paperwork to pickup. The service was door-to-door. They pick her up from London, sent her to airport and arranged for a local agent to clear the HK side and sent her to my house. Crate and air ticket included in the costs. They charged me around 1300 quid for everything. PetAir had boarding services too. I would recommend them.
