That is awesome but we do so much less than you.  We freeze corn and squash, and sometimes the pole beans, but that's it.
We just make a list and get the seeds in March/April, whenever we see they're out.  I used to make large orders on Burpee or one of them seed/plant places.  I also use to start tomatoes and marigolds in the house in March but I quit doing that too.  We lessened how much we plant so for tomatoes, just want one of four different kinds. 
What things do you dry?   I dried some lavender but then the plant died.  I give up on those.
