Do some data entry -- 2

I am a headhunter and looking for someone to do some ad hoc administrative work. Work will include sending on my behalf standard letters, confirmation of interview appointments, compiling new contracts from a template and producing invoices for clients, and updating a database on excel such as recording client name address telephone number and email address and similar information for candidates. I anticipate this to be a regular amount of work in the region of 3-4 hours per week on an ongoing basis.
