Real dolls are available from Abyss in the US. They have a fairly straightforward order and delivery process which works for the UK too.
Their prices are shown on their site.

The UK border force will add on various taxes when the package arrives in the UK. Currently a rule of thumb would be to add 26% to the cost of the doll plus shipping.
For sales or ordering information contact Joe 'sales (at) realdoll.com' who is quick to respond to email sales enquiries.
