Are you a commercial pilot? Then you should not pay for time, you should get paid for your time. Get your MEI and instruct. The benefits by far outweigh buying your time. As far as how many hours you get...well that all depends on where you work. Where I worked, they were so in need of MEI's that all the students on my schedule were multi. I left for the airlines with 800 and 200. My friend left with more multi than single. Also, this is quality multi, not just flying across country!
