When it came to sending out baby announcements, we opted to go with 2Peas1Pod. It's a small business set up by a mom/graphic designer, and we were very happy with the results. Another designer sent me a link recently to his baby announcement business called 5 Star Baby, where he makes personalized birth announcements that look like movie posters. It's a cute idea, and clever enough without being too "clever" (anyone ever gotten one of these Hershey candy bar "HERESHEIS" announcements?). I can't vouch for it personally, but the business looks similar to 2Peas1Pod, with personalized service and attention, and it's probably something that most of your friends and family haven't seen before.
