This is 10 hours of work to see if this will work as a full-time job.
What I do is build on-line presence for off-line businesses.
The ideal assistant should have the following skills:
Able to do simple web design with an artistic ability to clean up customer websites
Able to setup wordpress, Joomla, Zen Cart, etc., including installing themes and adding plugins.
Able to write sales copy.
Able to add listings to vertical directories
Able to write press-releases
Able to manage an Adwords campaign
Able and willing to run Scrapebox, Bookmarking Demon, High Page Rank (Brute Force Linking Loophole) and ArticleBot. I will train you.
Able to write blog posts that are proper US English and are relevant to popular topics (celebrities, breaking news, etc.)
The actual trial job will be to:
Write a short press-release for a business
Write some sales copy for the same business
Write spun blog posts on popular news items, then a scrapebox session, then run Demon.
These should be done concurrently.
For gauging your ability, please write a short blog post for a hot news item or celebrity news. First page on Yahoo will give you plenty of ideas.
