go to a show always pigeons for sale...where do uyou live? Might know someone! I have bunches right now! Go to swaps and flea markets...not usually show birds but a good place to start and you never can tell who might show up getting rid of culls and I will tell you that some folks culls are better than others show birds!
To anwser your question yes, Stromberg's hatchery sales pairs of pigeons but they are pricey and the shipping just isn't worth it. The best way to aquire birds is directly from a breeder. I have Birmingham rollers and I aquired my start by driving about two hours to a breeders house. You can't just pick up good performance pigeons anywhere, but since you are wanting them for meat, you might be able to find what you are looking for at a nearby bird swap or flea market.
