Virtual Assistant/researcher/writer

I'm looking for a virtual assistant to help me with a variety of both personal and professional tasks. Here are a list of responsibilities as of now.

- research: everything from the best video hosting providers to hot spots to eat dinner
- scheduling: keeping both my personal and professional calendar up to date, making reservations, and setting appointments
- writing: I work in the trading/investing space and will be looking for someone to write updates and papers on this subject matter.
- phone work: dealing with clients and general tasks that will involve phone calls.

Excellent English, both written and verbal a must.

Fast turnaround time. Most of my projects will need to be turned around in 24-48 hours.

Experience and or interest in economics, trading, and investing is a plus.
