Work on Laravel SAAS project

I have a SAAS web application built in Laravel that is partially completed and needs additional work and improvements (the previous developer has other commitments). All of the requested updates/changes are in the attached Word Doc. The website is meant for teachers or businesses to provide microlessons to students or employees that they would access through their phone (progressive webapp most likely, no plans for native app). The teacher buys a subscription and then creates lessons (right now can just add text, youtube videos, and images, but likely quizzes in future). The students register using a link the teacher gives them, and they can only see their teacher's lessons. The teachers would likely build the lessons on a desktop, but students would likely access lessons on a phone. The basic structure for building lessons, adding topics, adding content and displaying on front end is built, but you need to add the subscription and user account management functionality and some fixes and changes, all listed in attached document. You can see a basic version here: [login to view URL] User: test@[login to view URL], pass: password; and see what the student would see here: [login to view URL] I will send the source code if you request it in your message and are clearly qualified to perform the work.
