You can do it cheaper than 6k trainings 1k, good second hand wing 1k, motor 1.5-2k (might need a bit of tarting up)
Helmet anything ce marked will do, bog standard walking boots,good coat, jerry cans x2 (3.99 each petrol station) forget about gps and stuff to start with you won't go too far away from your field for a good while.
eBay isn't the devils work despite what most people think! I got my wing fom eBay for 1k and it's bloody great! (caution is advised obviously) you can get some great stuff cheap and the older you go the cheaper it gets.
You could do it for £3500 or cheaper if you really looked about
