I would make a HH review for a 10-25NL player, I would review database in couple days, mark hands and leave notes for every hand that I think is mistake, etc. My main game is 50nl, probably moving up 100nl soon playing on MG network so cant post a proper graph, but Im doing very well, just struggling to put in alot of volume (still a mental game fish;p). I would take probably like 150-200 bucks or smth.
My 25NLz graph from PartyPoker:

6.5bb/100 after rb. btw, I improved alot over the last few months cuz I'm studying/playing full time for that time, so I guess I would reach like 9-10bb's/100. My main purpose of doing this is to improve my self, not to earn money. If someone intrested and need more info PM
