Rifleman Archive

I'm currently a near master TKA on Starsider. And I am planning to go Master Ranger/Rifleman on a different server (that has T-21s) today is what? August 20th, I go back to school Sept 8th. How far do you think I can get up the Rifleman tree within that timeframe? With about 4-5 hours a day of playtime? I'd appreciate any insight, and even any suggestions on where to go / strategies. Thanks a lot.
