n.s,
I know someone who will get you through to a very high standard and in relatively short order (maw 1 week) provided you go prepared. PM if you'd like more details
6 weeks should be plenty provided you prepare properly, go to the right school and get the right instructor(s).
I went from nought to PPL (including all the groundschool) in 3 weeks, my brother did all the flying in 12 days (and the groundschool only took him an additional 4 days) and no that wasnt in the US, I did mine in Kent and my bro' did his in Scotland...it can be done
