The Flow hive does not require a particular type of bee, well except of course it should be a honey bee! Not being facetious here, some people like to keep native bees, mason bees and other pollinators. The Flow hive is totally unsuitable for those.
I agree with all of the comments above, but what I would recommend is joining your local beekeepers association, and asking them about their bees and where they get them. They are likely to know the good local sources. Failing that, you must have a local bee supplies store, and their staff are likely to know good local live bee sources.
There are several good reasons to buy bees locally:
- Your bees will already have adapted to your local climate and forage
- Your bees will not be traumatized by a long journey in an uncomfortable box, being shaken around
- You are supporting your local beekeeping economy
- You will have a local point of contact to ask about installing and caring for your bees
Finally, I highly recommend that you get a nucleus rather than a package or a swarm, if you can. Although these often cost twice as much as a package, they are much easier to install and establish in a new hive than a package/swarm.
Good luck, and keep asking questions!
