Members only scheduler

My company is a 1 to 1 tuition agency and I am building a website in which there is a login page and a members-only schedule page that can be used by both parents and tutors. I was wondering how do I create a scheduling page in which the tutors and parents can see their own schedule and their own fees. Whereas, I can see and make all the schedule by assigning the tutor’s account and parent’s account together. I would also like to see all the fees I have to either pay or receive. Lastly, is there any function that can send out emails at the end of the month requesting money from the parents.
Thank you for your help!
