Service & price editor - Appointment calander

I need a backend to output html on the content area of prices pages for my clients. Site owner to input the necessary information & the results to be displayed on the prices page. I just need to be able to paste code into the html page where I want the data to be output. Appointment request calander with backend (can go in same directory as above) where site owner can list multiple stylist names for visitors to chose from and also time & date calander. The request gets sent to the site owner's email address (to be defined by the site owner in backend).
