OP - have you thought about doing a bit of Dev work? It's quite easy to pickup the modern languages as there's quite high level, I know the commute would be a bitch - but a junior Dev in Brighton or London would get a reasonable wage, and after a year or two (if you take to it) reasonably decent money is on offer.
I'm in a perm role at the moment - but if I went back contracting then 500+ per day for a Java Dev role would be quite achievable in London, and at that kind of rate I could put up with a commute from Eastbourne and probably do a couple of nights a week in a cheap hotel or a B&B to take the sting out of the commute a bit.
