Online marketing professional required

We are about to launch a website offering IT support services to small businesses within the M25. We need an online marketing professional who can provide us initially with a clear marketing strategy (with costs involved of using different types of marketing approaches) including PR (both online and using traditional media), online banner advertising, PPC management for Google Ad Words and social media integration and management, mainly LinkedIn. As it is a new website, it is important to drive visitors to the site by using the above methods of marketing, and possibly any others that you think would work.

Is this something you can help with?

We need someone who can initially help us with the launch of the site, and then ongoing marketing help, possibly on a monthly/bi-monthly basis.
