I love bumbing old threads! 
If someone is struggling in PLO2, there are usually 2 reasons. One is some major leaks in fundamentals. Like opening hand ranges, when to push stacks in for value and when to fold pretty good hands etc.
Other is mental issues. PLO2 is very different from PLO10, as there are usually tons of villains in pots, and hald of them can't spell F-O-L-D. So you it's pretty hard to make money on just open raise and make a continuation bet. So you have to change your gameplan a little what it might be in PLO10.
As in "higher" limits the 3 most important things in PLO are position, position and position. In PLO2 those 3 things are value, value and value. 
I know it sounds silly if someone asks for private coaching in PLO2, as usually all the private coaching advertisements are for higher limits and $100+ per hour. But I have given some private lessons in micros, and for very affordable prize. I think that 1h or 1,5h coaching can give a lot. If I watch 30 minutes of someone playing like 3-4 tables, it's easy to spot those major leaks (and if someone is struggling in PLO2 there ARE some major leaks) and then those can be discussed for another half an hour or so. So for 1-1,5 hour coaching, the student knows his leaks, why they are leaks, and how to repair them. If someone gives him that for few bucks, it's pretty good thing to start.
