Asterisk PHP AGI Programmer

We are looking for help in building a reminder call system which will interface with php web interface. The php web interface should allow users to put in phone number, appointment time, Doctor they are seeing and date. It will contain a table of structure CustomerId PatientId Phone # Patient Name (first & last) Appointment date Appointment time - The reminder call system needs to read the table, pick the first customerid, call all the numbers under that, play a message constructed using text-to-speech (message will vary based on customerid). - A typical message will go something like 'This is a courtesy reminder for {john doe} about appointment with {Dr. John Doe} at {Familyt primary care} on {December 26, 2008} at {9:00AM}. Press 1 to confirm the appointment, 2 to reschedule and 3 to repeat the message. Update the status in table for the patient - Repeat for each clinic id. Installation - Install Asterisk server on a preinstalled linux server (will give you root access and static IP) Configuring database connection - connection to mysql database Call - call numbers from the list; whether it is a live person or voice mail, application needs to speak the appointment reminder message Text-to-speech - the message will configurable as a voice+text combination. Confirm - After playing the message, the patient will press an option and it needs to update the status field in list with the option pressed (except status 3). If patient did not press any field, leave status field at 0. Multiple clinics - the message will vary based on different clinic and a login page for our customers to login and see the results of the reminders from the options pressed by the user. We are very technology savvy but have not done any asterisk programming in the past. example websites to understand functionality: patientcall.
