Here's a thought...at this years Cannes film festival, there were just over 600 participants from the USA listed in the 800 page Marché du Film guide. If you made 2 phone calls every business day, you will have contacted every American-based attendee within a year's time. If you parsed out contacts that did not fit your slate, you could no doubt cut that time in half. Get busy!
Absolutely love this post, Joe. All about strategy and commitment.
