Medical (veterinary) Personal Assistant

I am interested in recruiting a long term, full time assistant to help in a variety of tasks including:
1) Managing the creation of a regular email newsletter. The content of the newsletter will be somewhat technical and third party writers will need to be sought (we will give guidance as to who to approach).
2) Researching and summarising medical journals (the subject matter will primarily cover ophthalmology)
3) Potentially medical transcription of letters which will include adress and clinician qualification look up (guidance as to where this information exists will be given. The input of images into letters would be of interest.
4) Experience with a Client managment system would be an advantage
5) Co-ordinating a muticenter clinical trial which will include communicating with other clinicians and collating information collected
6) General PA duties
7) A high standard of written and spoken English is required
