I'm OK to wait two weeks. I'm pretty sure they'd be OK as long as I sent it overnight - I'll stuff an Expresspost pack (bubble wrap envelope) with as much as I can. It should be OK because it will spend overnight indoors anyhow in the Canada Post system. The riskiest part would be when they deliver. If it gets left outside for more than a few minutes I would think that would be the end of it. So it would have to be a day where someone can be home when the mail comes so it can come inside right away. I would think I could get you at least a dozen plants... The Expresspost packs cost about $10 (that includes the overnight postage). So if that suits you, let me know and we can work out the final details via PM.
Thanks!
