I'm a freelance videographer and I'd like to sign up to an online agency to gain extra work. I am already on peopleperhour.com and other sites such as mandy.com, but would like to find something more specific for video and London, or atleast the UK. I currently work on a variety of videos from event, product and how-to, corporate, special occasion etc. I'm not currently looking for TV work as I am not experienced enough.
As I have never signed up to one before and I don't know how successful it would be, I would also like to find somewhere that take a percentage of earnings, rather than a fixed monthly fee. However I'm willing to listen to advice if people think this isn't the way forward.
