Ask HN: How to find a copywriter/copyeditor?

Hi HNers!

I've started blogging a few months ago, and it's working out pretty well for me. I'm planning to invest more time and energy into my blog for the coming months.

However, writing is really hard for me. I'm not a native english speaker, so it takes me hours to write a short blog post and I probably make a lot of mistakes.

I think both of these problems could be fixed by working with a copywriter/copyeditor. What is the safest and cheapest way to find a good copywriter/copyeditor? Should I look into websites like odesk.com?

Thanks!
