That’s entirely your decision.
There are some excellent CV writers in the UK, and I’d never tell you otherwise.
What I can say is that when you work with me, you work directly with me from beginning to end. We have proper conversations; we work through your CV together; I include unlimited revisions; I teach you how ATS works; I optimise your LinkedIn profile; and I don’t stop until you’re happy with the finished result.
If that sounds like the sort of service you’re looking for, I’d be delighted to work with you.
