I cut my own hair every weekend. I’m in the military, though (and no, I don’t just shave it). I found that I do it more to my liking (and consistently) than the barbers I’ve gone to, it only takes 20 minutes, I don’t have to pay $30, and I can shower immediately after. I use a 6 (3/4 inch) on top, a 3 (3/8 inch) around the curve transitioning to the sides, and then fade down from there, 2 to 1.5 to 1 and finally .5 (1/16 inch) around my ears, side-burns, and most of the back. Keeps everything clean, I always look good, and I spend about $40 every year or two.
To your second point:
I typically will reply with just the bulleted points they didn’t address and then keep sending it with less and less bullets until either they answer all points or stop replying… after the third or fourth reminder email. I make sure the previous emails are in the string and never change the title.
