I'm looking for someone to do a simple research on London based digital agencies. I need a list of all (or as many as you can find) agencies that do one or more of the following: SEO services, PPC services, Social Media marketing services, Web/e-Commerce development, Mobile app development, and Video marketing services.
More Importantly, I need PRICES... I know many of these companies will be quote based, but some will provide packages and I need to know the price range of these packages.
I've attached an Excel sheet to be filled in... there are a couple examples in there already.
