Appointment Scheduling & Payment Booking APP for Mosets Tree

What is needed for (Appointment Scheduling and Booking Payment systems for Mosets Tree Directory Listings) -A personal appointment scheduler for each Mosets Tree directory listing that a user (public user or registered user) can use to book a time slot and pay the Directory Listing Person(Profile) for their time/service. -A control panel for Registered Directory User (service provider) and also a control panel for Guest Users (customers) that allows control and viewing options for bookings and payments. (all up-to-date info for customer and service providers with an email system for direct person to person contact) There also has to have a way for front end usage of the system (not all back end work by admins) - it needs to be this easy: a new user pays membership to website, registers to joomla through OSE membership, adds their directory profile within Mosets Tree and adds the entry into correct category. Then within the newly built application they are guided to enter their bank info, etc. into the (Mosets Tree APP) and set up their appointment scheduling options (days, times available, price, services offered, etc. *This personal appointment service information will also be in the Mosets Tree directory listing for people to view AND search criteria for. So it would be useful for this app to be integrated in a way that allows for displaying custom fields from the Mosets Tree Directory.*) Then their profile and MTA schedule can be seen by X# of users. If a visiting user sees someone in the directory that they want to book an appointment with they need to be able to do it or be linked to it directly from that person's directory listing (profile). Essentially, it needs to be easy and direct for someone to come to the website, see a person they want to purchase time and service from and book the time and service. Notifications (email and control panels) would be preferred for all points of process in the booking (purchase, cancellation, changed time, payment sent, payment completed, etc, etc.) Just imagine what you would use and would want if you were scheduling time and paying for a service from a directory of service providers.
