Maintain B2B social media presence on Facebook, LinkedIn & 6 x Twitter feeds

We have a B2B non commerce website promoting our professional services. I'm looking for someone to take over the day management of building our social media presence for a fixed monthly fee. I only want someone who has experience of this kind of work in the Professional Services sphere for UK based accountants, surveyors actuaries, barristers, solicitors and/or IFA's. Please do not waste your & my time if you do not have this experience.

I'd like this to encompass:

GENERAL

maintain Twitter lists so as not to clutter up main feeds
