I'm an IT project manager and can't decide whether to switch from being an employee to contractor.
I decided a while back I'd move into contracting for the freedom it affords and the ability to charge higher rates. Re freedom, its not just the flexibility for personal reasons but also to boost experience with different companies.
(I know the financial perks are less than they used to be but I'm looking to earn as much as I can in the short to medium term)
I'm based in the South East and expect to have London based clients even if I don't work in London myself (but this is likely).
But , the average day rates for IT project managers seem to be about £500 which seems low. As a f/t employee I'd expect to be earning at least £50k (possibly more?) although it seems to be that the researchable earnings figures come up low compared to what people are actually paid 
Can anyone advise through experience salary expectations of a mid-level IT project manager in London/SE please?
I don't feel I can ask recruiters I speak to in real life but think like a lot of women I've undersold myself in the past. Looking online, I've gone from certain about becoming a contractor to sooo confused!!
