General Virtual Assistant

I need someone who I can assign general, basic tasks to on an ongoing basis. These tasks will range from typing up documents, researching online and other general admin tasks. The tasks will not be very complicated.

This will be an ongoing ad-hoc assignment as and when I need someone, some weeks there maybe nothing, and other weeks there could be a couple of hours work.

I am looking for someone who has a good command of English if not native, and someone who can work to deadlines and communicates well.
