Get your ratings as quick as possible. Study hard. Get your CFI and CFII and instruct to build up plenty of time. You won't be able to fly 135 until you have 1200 hrs. I really dont think it is worth it buying your own plane if you already have your private. You'll have to do 10 hrs complex for your commercial (which the warrior is not) and your CFI checkride in a complex airplane as well. You'd be better off spending that money on buying a cheap twin. Good luck
