I have about six websites and the income is fairly decent for a one-person operation. Because I am wanting to concentrate my time on projects other than Web publishing, I am looking for someone to work on my sites, as I am reasonably sure the revenue can be doubled with some work.

The tasks I am looking to have done are:

-- SEO
-- add content
-- updating content
-- tweaking AdSense
-- using Google Analytics
-- expanding the affiliate programs
-- link building
-- ongoing maintenance

I would also like to find someone that can take the initiative to make suggestions for improvements and research other ways to improve.

I've considered hiring a virtual assistant from overseas, but I don't know that I want to take the time to train someone and more difficult still is finding someone with initiative to go beyond just taking orders.

The other choice is hiring someone who already knows what s/he is doing. I know that's going to be a lot more expensive, but it may be worth it.

The questions:

1) Is there a service that provides most or all of the above listed criteria?

2) Can people to fit my needs be found at places like eLance, Craigslist, etc.?

3) Other thoughts or suggestions?

Thank you!
