We can't discuss poker training sites on the forum, but I would advise against wasting your money on a training site & sharkscope with such a small bankroll. You really don't need either to beat low buy-in levels for a solid ROI.
Reading the FAQ, the forum, and posting hands will help you do that.
We also can't discuss rakeback on this forum.
You should probably go with PS or FTP for a buy-in near $5. If you can get rakeback or a bonus on one of the sites that will certainly help.
