Well spoken Craig mate these southerners brains can't handle that much north east in one post. Just throwing words out there in any order and putting aye on the end haha!
As for the OP, everything has been covered, get insurance, get mats from local schools for free, dont mug yourself off with the price, be straight with your instructor and potential students. Do all that and you'll be reet.
Best of luck fella hope it all works out sweet for you.
