Building content for my niche I know little about

This is certainly a tricky part. I know very little about Kung Fu, but the internet has made things a lot smaller...
I decide to write down what I would want to know from a martial art site if I was arriving at it and wanting to learn. The site needs to be targeted at someone that's a beginner (hence the keyword "learn Kung Fu"). Also, I don't have the time to create all this content.
This is when decided to join freelancer.com. An incredible website that allows you to post a project and people bid for the work. This was my first time using it and I was blown away.
I created the spec for the content I wanted written which was six articles covering the history of Kung Fu to fighting techniques and meditation. Within 15 minutes, I had about 10 bids already placed and a few messages directly to me with freelancers telling me why I should pick them. The information wasn't overwhelming either, because I could easily see how they wrote to me (to determine if I thought their writing ability was any good) and also view their profiles to narrow down and create a shortlist. After creating a shortlist, I could request past articles from freelancers too.
It didn't take me long to decide on a freelancer and the content cost me just $50. At the moment, the freelancer has sent me through 4 of the 6 articles already and it is great. His writing is far superior to what I could have written.
The only downside was that my freelancer had no SEO experience like some of the others did. I'm not concerned though, because I can go through the articles myself and insert the SEO I want.
While I'm waiting for the rest of the content, I've simply been organising my site and getting used to the theme I'm using. I'll concentrate on creating backlinks and really pushing the SEO when I have my content. Then it is the exciting part of seeing if the website makes it up the Google ranks.
