Administrative assistant

I am looking for a highly organised and effective person who can:
• Create/edit databases and spreadsheets
• Edit/improve ppt presentations
• Effectively use MS office applications
• Proof read letters/website content etc.(good literacy skills essential)

I may also need support in some research (finding contact details of people) to build databases, so you need to be comfortable on the phone. When work includes telephone calls they can be treated separately as expenses)

I am unable to define the regularity of the work but I am looking to build a long-term ad hoc relationship.

Thanks for your interest.
