Birky,
I'm mildly amused at the pay rates for a cargo "thing".
Jet, yep, you're on the money. Turboprop? Nope, that's closer to command pay. For an FO on a Shed flying freight, you'll start on about £14K (add in ~£2-3K's worth of allowances). You'll be flat out taking home £900-1,000 a month. Now do the budget.
