seeds for garden (Berks County)

just read about some interesting new varieties I'd like to try. all from different companies, so postage would be more than seed. If anyone could spare a few of any of these varieties I would appreciate it. Have lots of seed (flower, veg, fruit, herb, tree) to trade. Looking for: goldilocks acorn squash, creme brulee shallot, artisan blush tomato, red sun carrot.
