Check out these two tutorials I created on how to use the Divi Theme and Builder to edit your website content. Mainly I created them to show clients how to use their website, but if you thinking about re-doing your website or starting from scratch and are unsure about being able to edit your own content, view these videos to see how easy it really is.
Here is another one on how to create and post a blog post.
I do have lower cost packages for designing and setting up a custom WordPress theme which I can then hand off to you to create your page content. This is great for those on a budget who want a professionally designed website affordably.
