Social Networking / Marketing Support

We are The Greenbank Partnership www.thegreenbankpartnership.co.uk - a small, successful skills (leadership+sales) training consultancy with a great set of solutions and solid track record with blue chip customers. Now looking to further expand in 2012 and looking for some expert support in lead generation to build a solid pipeline. In particularly fully leveraging our web site, Linked-In, Twitter, our own blog, network, existing/past client lists etc. It could expand to an ongoing part-time role with fuller marketing responsibilities. We are looking for somebody who is relatively local to us (Surrey/Hampshire/London) and who has experience with other b2b work of this nature. Examples of past work and immediate ideas from looking at our web site and 'bulletin' would be helpful in selecting the right person.
