10 hours Ground school / Briefings……… . $ 400.00
You'll need a lot more than 10 hrs ground school to get through the PPL I would have thought.
If you want a job in the UK, then it is imperative that you do some flying in the UK. At the prices you give, ie $85 hr you could easily find an aircraft in the UK for the same price for a 100 hrs. Then you could get to know UK airspace/rules/airfield plus take your friends and family up to share costs, plus you can use the oppourtunity to check out UK commercial schools. Don't do it all in the US.
