I am a huge fan of outsourcing sites. To be successful in an online business you need to be able to leverage your time and outsourcing is a cheap way of doing just that.
I use oDesk for most of my hiring. I find I can get good quality article and book writers, sales letter creators and web site builders.
I use Fiverr for one off jobs like creating logos, blog headers, ebook covers. Fiverr is also a good place to get people to build followers to your Facebook Fan Page or Twitter account etc - $5 for 500 followers to start you off - how good is that!
As always you need to be careful with who you hire. My best tip is interview the applicants for each job on Skype, or at least get them to answer a short questionnaire so you can se how they write and how they respond. Once you have selected someone, give them a small job to do as a test.
If they are no good, cull them and find someone else. Before too long, you will find a good one, and you will be surprised where in the world they are based.
Good luck with the buisness. Focus on creating great content and outsourcing the things you are not good at or are basic tasks that others can do just as well as you.
