best means to oursource

I am looking for an outsource company that you pay a flat fee to once a month. The virtual assists will need to be able to do the following:

Article writing
Ebook writing
Sales and email letters
Web and graphic design
Wordpress plugin and theme creators
Facebook app design

Various SEO:

1. Cross-linking posts and pages in one website
2. Forum posting (meaningful posts that add value to the forum)
3. Press release submission
4. Article marketing
5. Submission to directories and search engines
6. Social media marketing, i.e. Twitter marketing, Facebook marketing, buzz marketing, myspace marketing
7. Creation of optimized profiles
8. Posting comments on related blogs or websites

This is the main things I need currently, if your able to redirect me to a web site that offers virtual assistants like this then I would be forever in debted to you. I would prefer somewhere that is cheap yet very good work ethics. I hear people from the philippines are the best, however I don't know for sure myself so a little information regarding this would be nice also.

I appreciate the replies I will get and the help from my fellow warriors!


Regards,

Mr. Skid Roe
