Your plan of action should include a schedule. You should have daily objectives and write what you need to do each day to reach your objectives. You've already set your target; now you are aiming for it. How many blog entries will you write in a week? How much time will you devote to doing SEO and driving traffic to your blog?
Your second step should be market research. You probably already have some ideas in mind, but if you don't that is okay. With market research, you're deciding what you want to write about and how you want to write it. You'll want to sell things or advertise for things that people are looking for on the internet.
The third step is choosing where to host your blog. Look for features that will make your blog creation simple and fast. If you are tech savvy, you'll have more options since you can upload your site via FTP. Otherwise, look for a host that offers a simple interface.
