Say you are well established with 20 years experience in forensic work, what's the top level of pay you can expect in the private sector?
It depends. Mainly on what you actually do. Assuming you report complex, serious cases, about £45k as a guess. But most will get less than that, and simple reporting will be about £25k. That's mainstream forensics - I don't know what the figures are for computer forensics, but that last pay-rates I had for West Yorkshire's computer crime unit were about £28k tops. I'd expect private people to make rather more - possibly a lot more.
