I was an IT contractor for a good slab of my career, and am now a pimp...
I actually claim credit for popularising that term in the early 1980s when I saw the view Mum2FunkyDude talk about.
With my pimp hat on, I suspect that he can get more than 40ph, but that depends a lot on what he does... ?
I must say I would need a lot of convincing that any job was "for life". Seen a lot of "lifers" looking for jobs.
I can't imagine any IT job is that way, including the Civil Service or a large firm.
Also he stands a good chance of being forcibly outsourced, keeping his current job, but for a different employer on worse terms.
All jobs, especially IT ones go out of date quickly, and as a contractor, you can make it less bad. That costs...
He needs to join whatever user groups exist for his speciality.
Those who talk of making very sure you have a reserve of cash are 100% right. It goes up and down, occasionally quite violently.
I guess I averaged 40 paid weeks a year, so I'd equate that to 65K per year.
He also needs to diversify a little. I have a habit of pushing Excel at people. There is an amazing shortage of competent Excel drivers. The money isn't wonderful (last one we did was 450 per day), but it can get you though rough patches.
A good accountant is pretty important, I've had the same one for more than 10 years, (Barry Whiffen), and can furnish contact details if you want.
