If you haven't already you should start building an email list. By building a list you'll be creating an asset of people that you can talk to and offer something for sale. Typically you need to offer something free in exchange for an email sign up, this is what's called a lead magnet. You should also create a digital product to sell as a test. I recommend bundling some of your past blog posts into a PDF. You could offer it directly on your site or better yet offer it immediately after some one opts into your email list. This is what's know as a tripwire offer. This also gives you the advantage of segmenting you list into buyers and non buyers. Let me know if you have any specific questions.
