That's fine, but pluck sensible figures - you cannot undercut your suppliers, so if it is £150ph you need to charge at least £75 for a 30 min t/l - otherwise you will get people twigging on and buying 90 trips off you to do their PPL, that will REALLY p off your suppliers! As said, I wish you luck, but endless you have something special on the marketing front I suspect you will struggle to make this work in competition with the big guys!
