High converting sales funnel landing page for an online course

I have an online course currently running on Systeme.io which has made some sales, but could do a lot better. I'd like someone with copywriting and landing page design experience to either build a more compelling sales funnel directly in the the systeme.io software, or deliver it in another format that I can set up in the software myself.

I can provide some testimonials, a link to the existing page, some photos, etc. I just need you to create a persuasive page that will increase conversions.
