Remote admin support for a one day course being held on 21st September

Estimated duration: not set
Description: I am holding a one day careers event aimed at other professionals within my field in London on the 21st September. I need admin support with the following:

1) Compiling a table (as a google spreadsheet, so that it can be shared with me) of all the attendees and their contact details, and updating this as new attendees register

2) Emailing all attendees details of the event (e.g. updated timetable and location)

3) Emailing all the speakers with details of their slot. payment and chasing them for their lecture powerpoints

4) keeping an overall record of income and expenditure for the event, and sharing this with me via a google spreadsheet

I need someone who is able to work at weekends (including this weekend) and who has capacity/time to commit several hours as soon as possible. This is essential. If you don't have the time to start work on this straight away, please don't make a bid. Also if you don't work weekends, please don't make a bid

Once the above tasks are finished, there will be more relating to this event (and post event e.g transcribing feedback).

I will need someone that is professional and discreet, as they will be dealing with the personal details of registrants. I will also need to know their full name and contact details, preferably in the form of a CV.
