Personal assistant

I own a range of business in east anglia from hotels to media companies and whilst I employ my own team I have a range of tasks that I need to get done on a monthly basis such as:

Reviewing a range of my websites to check content etc
I'm planning to run some boot camps at one of the hotels - need it researched and a local team put together to deliver it
Mystery shopping tests
Dealing with customer complaints
wide range of research jobs such as at the moment I need a list of people who own conservatories in east anglia for a new venture I'm launching
Posting and managing specific jobs on here such as telesales
Writing to people who have failed at interview a personal response

You will simply bill me every month for the hours you have done - any urgent work will be done by my team so no real time issues
