Another option if you have no commitments in the UK.
Go to the states and convert your license to an FAA ATP. Cost $2000-$3000. You could then work as a banner tow pilot or similar.
There are a couple of companies in Florida that will sponser your visa for up to a year and pay you $20 -$30 per hour whilst working. I know of one company looking for 40+ banner tow pilots. Another option is to then get a CFI rating. Plenty of instructional work in the states and you will get the hours in.
