reliable source for beneficial insects?

howdy folks! i was discussing beneficial insects with the boyfriend recently. he said we get tons of ladybugs, and i mentioned lacewings and mantids. he's interested in getting praying mantis egg cases...and i'm all for it. what would be a reliable source for them in the US? i'm in Baltimore, so if someone knows of a local source, that would be spectacular. i'm fine with getting them online, as well.
