Build landing page for online courses via thinkific platform

I'm designing an online course through thinkific platform. https://www.thinkific.com/

I need my landing page created to create a sales funnel process for people to sign up to my free course. It needs to flow, stand out and be simple to use.

Thinkific platform is an easy system to use and navigate around, but I just don't have time to do it.

Preferably I would like someone who has either used thinkific or something similar.
