GSM Modem API PHP MYSQL

I would need person that able to create API for me, that will connect with my 64Ports GSM Modem. Api will be receiving sms purposes and determined which Ports the sms from. Example the sms will received by Gsm modem with the specific port, then the Gsm modem will process with HTTP Callback to deliver on the API and recorded with the MySql database. Since I already got Sms Deliverer premium software can be used. Only needed the API and the HTTP call back that will send the SMS to the API from the Gsm Modem using the Callback.
