I'm definitely keen after being disappointed by a late pull-out of SMDI (stupid job...life would be so much easier without it...oh, wait...

LOVE the Embraer idea as those have become some of my favorite planes. Love the * Eastern Europe/Middle East DO idea by
RCyyz too...and a great idea to start in Canada since it's easy for North Americans, avoids the US insanity, and I happen to be basing myself there in 2010
A week is OK. More would be tough.
$1000 (for economy) is OK, $1500 probably do-able, a lot more would be tough.
That's for flights in the "core do"--obviously positioning where we're on our own can be adjusted to fit individual circumstances.
