You may be a better pilot at 500 than some other guy is at 1000, but you'd be hard pressed to convince me that you won't be a better pilot at 1000 hours than you are now.

As a CFI, your goal should be to avoid doing 800 hours of steep turns, stalls, and landings. That's exactly why you get your CFII and MEI and find students who need your skills. Instrument flying as an instructor is some of the best experience you can get until you get your first airline job.
