I'm glad you brought this up.

Firstly, regardless of the size of the response, I will uphold my promise and provide feedback on every single CV I get, it may take some time but I will deliver.

Secondly, as for a paid service, you absolutely hit the nail on the head as far as your concern about for fear that they may not have experience in tech / I.T. / programming or worse, that they'll simply find a couple of grammar mistakes and charge me a few hundred dollars.

This is the sole reason I haven't set up a paid service myself. How can you charge $100 dollars only to receive a CV that is essentially perfect or even convince your market that you won't just give generic feedback?

Send me the CV and I will do my absolute best for you.
