Mentioning company names on a CV

[HQ2]

I've worked with some pretty big brands on a self employed basis and was wondering about mentioning companies by name on a CV, something along the lines of...

Delivered x-value project for "company name".

or

Delivered x-value project for telecoms (or whatever) company.

I did speak to Rog about getting a proper CV made, but not sure what I want to do, how much I want to get paid or anything at the moment. More a case of having a look what's out there and hopefully having the bones of a half-decent CV to ping off if something looks interesting.
