Copy writing (by invite only)

Copy writing requirements:

I am looking for a flexible, on-demand and remote-working copy writer to support my small business through a busy month coming up.

The person would need to be:
- Excellent at proof reading (spelling, grammar and formatting)
- Familiar with advanced features of MS Word like 'styles', references and cross references, headers and footers etc (I can explain, but preferable not)
- Able to proof read, to web research, and occasional more administrative jobs
- A quick worker

Any marketing background would be advantageous.

Please quote an hourly rate, or for an estimated 10 hours work over month.
