Remote admin assistant to book meetings with colleagues and arrange venues

I need a remote personal assistant to:

1) email and ring my colleagues (about 7-10+ in total) to book appraisal meeting appointments for the months of January-March 2014, from a generic email address that I will set up
2) email different venues in London to book rooms for these meetings (I will provide the details)
3) confirm these meetings with me (via a googlemail calendar invite) and each of my colleagues
4) collate the above information in tables in a word document

This work is something quite simple, but I want someone who is meticulous about details and confirming bookings. Records through email threads need to be kept carefully. I don’t want someone who is very busy and can’t pay attention to doing this carefully. I also want someone who, once accepting this job, sees it through to the end.
I would prefer someone based in the UK. Please let me know what your hourly rate is.
Look forward to hearing from people who are organised, polite on the phone, professional about deadlines and commitments, and who have capacity.
Thanks, Deen
