I know there will be lots of folks that disagree with me, but why not just start a Blogger blog on your chosen niche? Use a custom template instead of the ones that are offered by Blogger, post 10 original articles that are related to your niche, and use a custom domain rather than a blogspot subdomain. Then, just do good SEO and maintain the site.
I wonder what people have a gains custom templates. You can always customize them and make them look better.
To write more articles that can help people,publish in your blog and republish to other websites with a link to your blog.
