Social Media Manager

I run a UK based accounting firm and am looking for someone to manage our social media - twitter, facebook business page, LinkedIn (company page and directors feed) and Google+ (which we don't really currently use at all).

Twitter account and FB page are currently used not too badly - but not in any consistent way so this is one thing we are looking for.

The aim of the role is:
1) Make our current clients feel loved by re-tweeting, sharing etc things that they are posting that may be of interest to others
2) Gain enquiries/clients from interactions
3) Help build a love for the business generally with UK small business owners
4) Show case us as experts in the field

It would help if you have some knowledge of the accounting profession.

This would be an ongoing role, ideally you should be UK based (but USA, Canada, Aus, NZ will be considered) and must have English as a first language.

Thanks
