1000 Calories a Day

Is it enough? Is it too much?
I have a job with very very high energy requirements, getting at least 1 hour of cardio and strength workouts every week day.
This doesn't include extra calories burned at work and my home workouts.
I want to drop weight as quickly as possible without getting shaky or passing out.
My goal is to hit 1000 calories a day. This will give me a deficit of at least 1300 a day, leading to 2.6 lbs lost per week.
This doesn't seem too drastic or unsafe, right?
Total weight loss goal for right now is 10 lbs, and reevaluate from there. That's only going to take me a month to get there!
 I have a feeling the weight will fall off much faster, because I am going to be pushing myself harder than I ever have before.

 I will not slip up. I will not quit.

 I will be empty and strong again
