How much will it cost to bring 2 cats to the UK from the USA under the PETS travel scheme?

I would just like to know if anyone has done this recently and approx how much it cost for the actual flight and PETS passport? Thanks very much!!|||Your main cost is in shipping (approximately $800 each), but it also requires time. Your cats have to be vaccinated for rabies, and a month later a blood sample submitted to the Kansas State University to get a qualifying titer ($60 each). At the point you get the titer, you count 6 months before you can go to the UK. Three days before shipping, your cat has to get a treatment for worms and fleas (approx $25 each, depending on vet), and has to get a USDA certified veterinary health certificate, $75, (may have to be overnighted to this vet).
