Arduino Programming AT commands

Here below, I will try to explain briefly and, I hope, clearly, the project that I have to realize and the problem.

Project

I need to create a system that detect atmospheric data by sensors and transmit them via GPRS / GSM.

To do this, I "assembled" an Arduino Uno and a GPRS / GSM shield model "Hilo Sagem."

At the moment, the Arduino is programmed to receive and convert the data received by the sensors into data packages for the GPRS / GSM Shield, and GPRS / GSM shield is programmed to send data packagets.

Problem

The GPRS / GSM shield fails to send multiple packages in series; after sending the first package, the GPRS / GSM shield enters in stand-by mode (stand-by mode is required for energy saving) and it cannot longer be reactivated to send the next package.

Need

I am looking for a programmer who is familiar with the "Arduino world" and that can:

- correct the software (software carried out with “AT command”) and provide "advices" for future issues

- carry out a proper software from zero also with other components.
