Arduino Uno/NB-IOT SIM7000e shield (DFROBOT) integration

We are looking for a Arduino developer to develop and test a module using an Arduino Uno and DFRobot SIM7000 Shield. We currently use a SIM800L attached to an Arduino Pro Mini and are looking at eventually replacing the SIM800 with a SIM7000 module that can perform the following tasks in GSM/3G and 4G (LTE);

- Receive an SMS
- Read an SMS
- Read the originator of the SMS
- Read and process the contents of the SMS
- Send an SMS/s
- Receive a call / hang up
- Be able to fetch the originator of the call.
- Dial a number
- Auto select Network via hierarchy (LTE -> GSM) for testing must be able to be forced to a preferred network.

We have a hardware setup, as above, that can be remotely accessed for development/testing purposes.

We want the code to be stored within a separate library so that the functions can be updated easily in the future without having to change the .ino source code.

Any further questions please let me know. Please provide quote for development via People per Hour.
