Heavy Flyer,
I needed to earn money for flying so I did my H.G.V. licence. I take home around £380-£400 a week. I'm out all week so I spend about £15 on food! There is tons of work available as there is a national shortage of drivers. You do need to be 21 though and the training will cost about £1200, but you can use your CDL to pay for it, and you can pay it back in a month!
O.K. it isn't glamorous but many good jobs take a while to get into, but you can start this fairly quickly and earn some cash whilst having a little adventure!
