I am just starting beekeeping this year. I took a course at Longwood Gardens and then signed-up for a 5 session hands-on beekeeping workshop. Both are provided by Jim Bobb who is a professional beekeeper in the Lansdale area for about 16 years or so [I'm guessing but I think that's the timeframe I heard].
I placed an order for my bees with him. He goes to Georgia and works with a company down there for a week or two to package bees and then he brings them back to Lansdale for pickup. As he runs a professional business and has been doing this for so long, I would think the Georgia bees are just as hardy here as NY bees. But again, I'm a novice.
His website is: http://www.pabeekeeper.com/
You can find order form for bees on the site if you're interested but seems you already have an order.
Hope this helps.
