PR Week in its April 7th issue ran a feature on freelance PR in the UK.
It carried the following stats:
Number of freelance PROs in the UK = 3,300
Market for freelance PROs = £200m
Av daily rate = £400
From which you can deduce that the average freelance PR earns around £60K a year and works 30 weeks to earn that figure.
A quick straw poll of freelance PRs suggests that this figure is rather high - or there are some freelanc e PRs out there earning six figure sums - nice work if you can get it.
