Great. Will you be having the puppy reared at a farm? There are a few reputable places for quality rearing, just remember, if you take shortcuts in the rearing, it's just money down the drain rearing the pup to breaking in age and finding out it can't gallop because it hasn't been properly fed/reared in spacious runs learning to take knocks with other pups of the same age.
Also never rear a pup at home on its own.
There are a lot of quality pups for reasonable prices for sale, you can look in the Greyhound Recorder, NGF or on Greyhound Data classifieds. It depends on what you are after, do you find it hard buying a pup because they are out of your price range? Or do you want to get value for your money?
