Help needed designing prototype using Arduino and GSM shield.

Hi,

I'm working on developing 2 prototypes to demonstrate to potential customers. One of these prototypes I want to base around an Arduino and GSM shield.

I have looked into writing the code myself but the learning curve is too steep and I'm keen to get this under way while the time is right.

I just wondered if anyone on here offers their services commercially so that I can concentrate on the rest of the project while the code is being worked on.

It isn't a large project, but within the field I have in mind could potentially be very popular.

Any assistance would be appreciated.

Thanks.
