Arduino GSM Temperature logger

Need a prototype for a project. My needs are:

Hardware

* An Arduino based PCB

* Two temperature sensors, preferably DS18B20

- The first temp sensor attached to a 1,1 meter long cable

-The second temp sensor attached to a 0,2 meter long cable

* A GSM shield, preferably SIM900 or other GSM shield that will work world wide

* Re-chargable battery, preferably standard size AA

* A battery holder

* on/off switch

* a box for all electronics

* a micro usb port

All those parts soldered and fitted in a box. No loose parts! Needs to be screwed into the box with temperature sensor hanging out and on/off switch easy accesseble.

Software

So, what should this thing do? Pretty easy. The sw should collect data from the two temp sensors once every 120 second and send the data in degree Celcius to thingspeak. The sw should be optimized to use a minimum of battery power. Some kind of sleep mode is needed. I should be able to insert my own SIM card and via the usb/arduino software enter the pin code. The source code needs to be well commented.

I will review your progress. First to see your HW shopping list, second to see the HW build, third to se the product working (preferably via a video or skype) and after that you need to ship the product to me in Europe.
