Social media marketing & general VA support

I am looking for someone who considers themselves an expert on internet/social media marketing & who can support me to develop our online profile.
Over time tasks will include:
Social media updates
Graphic design/sourcing images for profiles
Content creation for blog posts
Analytics
Basic video blog edits & upload
Content strategy involvement
Copy writing for website

I'd also like to use you to support our clients with the above but you'd need to white label your services.

As a busy consultancy offering a wide range of services we often get asked to do research, organise meetings or put together a powerpoint so it would be great if you'd be happy to step in and help out in these areas too.

I envision us having a trial period of a month to see how it's working out, starting at some point after Easter.

If you're interested in the post them please send me examples of online work you have done e.g. Facebook profiles & links to blog posts or videos you've edited.
