PCB - GSM - Modbus alarm board

I need a PCB board which is sending SMS to a telephone.

This SMS should be the message of the Modbus alarm code

It should also be sent a SMS when power is off.

The number on which should be sent,

should be configured about a SMS sent to the SIM of the PCB.

At first I need 5 prototypes and then I need 1000 piece for first order.

Price per piece for prototype should be under 50$

Price per piece for first big order should be under 10$

Price for parts are separated from the project price...

It should be powered by 230V
