Add features to LAMP website

We have a website built using this system: [login to view URL] We want to add the following features: 1. Create a feature where teachers can decide if the lessons can be booked automatically or if they have to go through approval first. 2. Develop an option for teachers and students to download an invoice; 3. Integrate 2FA authentication for login; 4. Teachers must be able to filter their visibility to students meeting certain criteria (e.g: country); 5. Two-way Google calendar syncing (push and pull); 6. The teachers need to be able to see the student's profile when they click it & be able to add private notes that the student cant see. These notes should also be visible/editable during the calls (a side panel next to the video); These are the first tasks we need. After completion, we will send you a new task list for evaluation.
