In all fairness although writing a CV sounds very simple, it is surprising how many people - educated professionals - just get it wrong. A recruiter will look at a CV for you, but if your CV is not well written (and accurately reflecting what value you have added/can add) you are less likely to get that recruiter's attention in the first place. If you really want peace of mind that you are getting it right and don't have enough free time to get your CV in order, 89 quid is worthwhile imho (not that I offer a CV review service).
