Welcome to Pprune.
If you have a job in aerospace, do yourself a favour and do a little overtime and use your skill to earn enough to pay someone to teach you.
Seriously: do you earn less than £20 an hour? (When you take a two-hour slot to give a one-hour-in-the-air lesson, that is what many flying schools pay their instructors.)
Then buy a X-Air for 4k - or maybe even a share in one.
Remember, joining a club at a local airfield will also help you continue the learning process. You will hear stuff that is priceless.
Otherwise, buy a second-hand paramotor. Teach yourself to fly it. Lose lots of money when you find you have bought the wrong thing, perhaps crash and break your back and lose your mobility. Maybe lose your job.
But, hey, you'll have some happy memories to look forward to! And you will have done it all yourself and proved Mr Darwin correct!
