Setup my online course with Thinkific or directly on Wordpress

Alright, I'm just about to finish my course. I have the videos, the outline and content, and the landing page content. Now it's just a matter of packaging it together add thumbnails and putting it on my website nicely. I got an affordable plan with Thinkific, but I'm also happy to put it directly on the website without the software if you know how to do it. (And I'm happy to pay more for that because you are obviously saving me money)
The website itself is built on WordPress.

P.S. It would be nice to have someone who really knows the most optimal way for a course to look.
P.S.S. The Content is related to pro-Israel issues. If you have any issues with this content, clearly it's not a fit.
