If your requirement is only creating WordPress-powered websites, then WordPress.com is the best place to access all the free resources. However, building a free website using WordPress will not allow you to enjoy online visibility for your portal. So, it is important to choose a theme that is based on SEO optimization. I recommend a website, https://www.themelines.com/, which has a wide array of thoroughly SEO-optimized themes. Themelines also provides you with the access to free responsive bootstrap themes for your WordPress site along with easily customizable templates.
