Social Media Strategy

I need a detailed social media strategy for a client whose PR I manage. They have no presence at the moment, but don't want to start and go down the wrong path, or focus not he wrong areas for maximum impact.

I need the plan to be structured professionally and well researched as it will be presented as part of an overarching marketing plan that he can implement. It needs to be customised for my clients particular business (restaurant) - 'off-the-shelf' plans will not do! He is pretty well versed in social media so won't be convinced by being told how many times a day to tweet and that's it!

Expertise in Twitter and Facebook essential, recommendations for 1 or 2 other platforms that may be beneficial would be an added bonus. Fbook and Twitter are definitely his priority though!

If you can direct me to any social accounts you help manage, or have successfully created plans for that would be great!

I need this produced by Tuesday 10th at the latest - please don't pitch if you can't do the work by then.
