On learndash plug-in on my word-press website help me edit the home page and add a cost of my course

I have a wordpress website where I allow learners to do my e-learning course.

I want a freelancer to help me to :

1. add a course fee, so learners have to pay to do the course

2. Add discount codes so I can give learners discount codes so they can do the course for cheaper

3. To edit the home page of the website.

I will give instructions.

The website is learnml.co.uk
