I have a few sites where you may want to guest post. I include you as an author on the site and link to your google plus page so that your photo shows up next to your post in the search results.
Then, you can list yourself as a contributor on your google plus page to the blog. Let me know if you can produce content (one time or ongoingly) for any of these blogs, content that is not already covered:
