Here are some ways I can think of to get guest bloggers. The answer partly depends on whether you're looking for well-known names in a particular space, or if you just need some well written articles by anyone.

• Write a post on your blog asking for guest bloggers. Let people know what your standards and review process will be. Get the word out on Twitter, Facebook, etc.

• Hold a writing contest on your site where you'll run the top few entries. This may be difficult if you have a new blog.

• Write bloggers directly who you enjoy reading and ask them if they would like to submit a guest post. You could also offer to do a guest post swap.

• Post a paid gig ($30 to $75 is typical per post I believe) on some of the blogger job boards.
