Ordering chicks in the mail is how a lot of people start out, so it usually goes pretty well. Local is easier simply because they don't have to be shipped, but you also won't know males from females for a little while. Integrating isn't too difficult, but goes easier if you have a separate place for the younger crowd. It also helps if you have at least three in the new group, they'll tend to stick together.
Looking at breed is important too. Your Polish are pretty laid back, and can tend to be picked on...so your next breed should also be laid back, so they aren't mean to the older birds. Although, all younger birds are picked on at first, which is why it's nice to have a separate area for a little while.
