Further to what everyone is saying about the IFR, get the bush time first!
Most IFR jobs fly very little to start with, so it''ll take you forever to get any time, and hours are what you need.
Likewise, two guys show up, both with 2000 hours for an IFR job. Pilot 1 has 2000 hours of bush PIC time and a fresh IFR ticket, Pilot 2 has 2000 hours sitting cojoe in an EMS 76. Unless there''s some serious personality issues with Pilot 1 he''ll likely get the job, and he''ll be a quick upgrade to Captain, and in my experience, will make a much stronger Captain when the upgrade comes.
Another thing to consider, Pilot 1 has been out in bush camps for the past 4 years and is looking to settle down and develop a steadier home life. Pilot 2 has been living on a steady, easy (in comparison) schedule , living in the Big Smoke, steady girlfiend/wife, going to movies/BBQ''s/Social functions on weekends and able to plan holidays, getting to friends weddings, etc. for the past ten years its taken him to get 2000 hours. Do you think he really wants to give that up to go back into the bush to get some PIC time in?
If the bush isn''t your thing, get it out of the way when you''re young.
Flying EMS is a blast and is very rewarding, and its an honorable goal, but if you get there too early, and you hear all the bush stories of your fellow pilots, you''ll regret your choice.
