I don't know any contractor who would even consider getting out of bed for that.
It seems like you and PAH have opinions on opposite extremes of the spectrum. I'd suggest that the reality is somewhere in between.
As with perm jobs, the rates on offer up north for any given skillset tend to vary depending on the expectations of the end client - and perhaps the cut taken by the pimp.
As a result, developer contracts around here can vary anywhere from £8/hour to £60 upwards for niche skills. From the standpoint of a seasoned contractor, it may be difficult to understand why a developer would go for a £25/hour role - but the fact is it represents a potentially good opportunity for both end client and developer.
With the benefit of hindsight, I can be pretty sure that if I'd been sufficiently gutsy to leave my poorly paid first perm job after 18 months to take up contracting, I'd have been over the moon about £25/hour and most end clients would have been more than happy with my skills and experience.
The thing many people don't grasp about the north is that those living outside the major cities can enjoy a pretty good lifestyle on a rate of £200 or salary of 35K - the rates on offer tend to reflect this.
It's not a great situation - especially when rates are pushed down by end clients getting a mentality of "oh - a web developer only costs £25/hour in the north!".
I can, however, see why PAH gets the perception of only lower rates being available - the majority of developer roles advertised on Jobserve/CWJobs etc do tend to specify £25-30ph or £225-250pd rates. For some reason, the higher paying contracts don't seem to get advertised nearly as much. It's only once you get a number of contracts under your belt and become confident at talking yourself up to pimps that these higher paying contracts become visible.
