Watch out for the replenishment if you leave goods on your PM though and you log off ~_^

There is definately not a cap

ask llaar how big his PM was on his 95million acre FFA country

as for your situation, I've only run a tmbr switch once, and failed horribly at it, but that was like 3 years ago.

depends how much stock you have to sell off, and how much time you have to sell it off..

have as little land as you need to jump

simple math is your friend. I'll do it if you pay me $10 :-P

Heh I guess there should be enough time to clear 40m food at 10k acres as ur first buy will be a big chunk of ur 2m but building costs will be too.
