Why don't you actually talk to some IT contractors and find out how much they're paid? 'cause frankly I seriously doubt there are many earning that level. Most will be between the £300-£400 mark per day
I work in Financial Services and the majority of IT contractors I know earn at least £500 per day. I have to do the budgets for the ones in my team.
As a highly qualified, and in demand Electronics Engineer (there's a shortage of us in the UK), not even I earn as much as £500 a day, nevermind £700 a day!
Right, so because someone who is in demand in a completely different profession doesn't get £500 per day, it's not possible for someone else to do so?
Please get your facts straight before posting stuff like that, you only reinforce the misconception that we contractors are earling loads'a'lolly... though we would if we could!! :-)
And by "we" you actually mean "we Electronic Engineering contractors who don't work in a bank", right?
Because that appears to be your only frame of reference here.
