Once your blog is up and running, it pays to spread the word about your site. Get involved with bloggers writing on similar and complementary topics. Comment on their blogs, join carnivals and even create response posts to big issues addressed by other bloggers.
One final tip: stick at it. A blog needs persistence. Book time in your diary every week to add a few articles, using inspiration from your list of ideas. Within a few months you should start to see more visitors to your site and clients for your business.
