Arduino Uno with Adafruit ultumate gps & Adafruit fona -- 2

The project is simple, using an arduino Uno, adafruit fona gsm module found here ( [login to view URL] ) and adafruit ultimate gps module found here ( [login to view URL] ) the unit will text its location when the word "where" is sent from any mobile phone. The unit will recognize what number sent the text and reply to that number. In addition, the unit will text it's gps location when a pin goes high to a predetermined number in the code. Lastly, if the unit has no gps or gsm signal it will continue to attempt to send the requested gps data until it recognizes that the location has been sent. The freelancer will need to provide comments in the code explaining every line's purpose. Please do not copy and paste from existing codes found on the net. The freelancer needs to understand how to write the code needed. I am able to write codes and have worked with GSM modules in the past. However, I'm having issues with getting the fona gsm to receive text messages and make an action based on that text message. I believe it has something to do with needing to be commanded to look for the incoming text.. perhaps AT commands are needed. I am able to call the unit and have it text me its location using an interrupt but I would like to be able to text the unit so that I can perform multiple task. I'm able to use the SerialGSM library and would like to use this library instead of using the adafruit fona library. Also I would like to use the SoftwareSerial library and the TinyGPS library if possible as I'm familiar with these libraries. Please do not bid on this project if you aren't able to provide what I'm asking for...

Thank you for reading my project requirements
