PHP Code Update

My organization would like to integrate Hitappoint scheduler directly into our EHR system. We have the developer license and access to the source code. The functionality we are requesting: 1) Creation of a client or staff within our EHR system would create the equivalent in hitappoint and port the equivalent data. 2) A link in our system would direct to a specific customer schedule in hitappoint scheduler. 3) A link in our system would direct to a specific staff schedule in hitappoint scheduler. 4) Staff logged into to our system would not need to login to hitappoint. 5) Customers would not have link into our EHR system. 6) Add Checked-In as an appointment Status with corresponding text sent to the scheduled Staff when the Status is Checked-In. 7) With the SMS turned on (only choice is Global On/Off), the SMS phone number is required to create or update a customer, thus all customers get text appointment reminders. Add capability to each customer to choose if they want a text appointment reminder. 8) Same issue with Email reminders (only choice is Global On/Off). Add capability to each customer to choose if they want an email appointment reminder. Hitappoint is written in PHP 5.2+ and MySQL 4.1 [login to view URL]
