English Cocker Spaniel Puppy Wanted

I am looking for a liver English Cocker Spaniel puppy, preferably a bitch. My family has had English Springer Spaniels from the UK for 30+ years, I am well aware of the requirements that go into loving a pup. I am currently living in London but will be returning to the states and would like to be able to bring it back with me then. My mother told me they must be 3+ months old in order to travel.
