Virtual PA

We are looking for an Assistant who can help us for the next few weeks.
Estimated hours will be around 8-10 starting as soon as possible.
We need some help with the following tasks:
Blog writing
Research for blogging
Website planning (experience with Wordpress would be a bonus)
Social media posting and planning
And experience with graphic design - such as social media panels, Twitter backgrounds would be preferred but not essential.
I'm looking for the best person for each job - which may mean the tasks are split, but should not impact on the hours as I can pass over more work.

We are a Virtual Assistance company that needs some cover due to staff illness - but this could lead to a more long term role.

Written English language to a high level is essential.

Please quote for your hourly.
