I wouldn't move from site to site, I would select a major site with good volume and get a solid feel for the game you play there. I know Tilt's $2 sng's have a .25 rake, just over 10%, and are extremely soft. As far as making $10,000 single tabling micro sng's, that's highly unrealistic.
I would recommend giving 4 tabling a shot, I prefer stacking tables. If you want to make money playing sng's you really have to multi table to make a decent hourly. At the $2 level you do not need a hud imo, the players are ridiculously awful as i'm sure you know.
Learn to multi table now at small stakes so you are prepared at larger ones. Use smart roll management and study and you should move up these levels in no time, if you can play more than 1 table at a time
