CS-DNA (and mishandled)...
Apologies now for slightly hi-jacking this thread to talk about Unix sys admin posts...
The market for sys-admin's - even with as little as 2-3 (+) years of experience is quite good: esp in London and South East. And by quite good, I think a figure somewhere in the region of £30-40K p.a. would be reasonable, rising to much more (I've seen sys admin posts for £100K+) if you've got a speciality. Sys admin plus a.n. other task - eg batch job scheduling / Systems Management / backups / san's / high availability systems / etc) is particularly highly valued.
My best recommendation is to go onto jobserve.com (and perhaps a couple more) and sign up for their automatic e-mail service. It will e-mail you for free every time a job advert containg your key-words comes up. You can be quite specific and can choose job type (contract or perm), location and salary. It puts you under no obligation but does give you an idea of (a) how many jobs there are out there; and (b) What other skills employers value.
