Do you have a heating pad?
You could apply the heating pad for a time and then wrap the carboy/bucket in a blanket. I would also try to get something between the floor and the carboy/bucket to reduce the cold transfer.

Gravity works well with mine. The slower rate of flow ensures effective cooling from 215 down to 50 degrees. I use my old IC as a pre-chiller in a bucket of ice water.
Just picked up a couple sixers of Short's Good Humans - it's a seasonal double brown dry hopped ale.
Love most everything that comes out of Short's Brewery.
That's what I thought based on my belief that they use a thicker mylar style bag. I always transfer my hops to foodsaver bags when I break into a pound bag.
Dragonmead in Warren is another good choice.
