Content transcribed various sources onto LMS training system

I am in need of someone who can transfer supplied content from various formats (power point, pdf, hard copy etc) onto a LMS online training platform (Thinkific) to creat our own training courses. The content transference is simple enough, the challenge initially may possibly lay in getting an understanding of the Thinkific platform, in order to place the content accordingly. This in a way that best suits my objectives and requirements, so a to and fro initially between us, until cohesion is achieved, and then it's a simple template going forward really..
This is going to be a progressive project, with several courses required initially, culminating in potentially 100+ courses within the space of 12 months. A slow burner.
The duration for each course creation is a variable, as some courses take an end user 20 minutes to complete, and others 6 hours. Your speed would of course also be a factor.
