Microcontroller and ARM SBC choice / average production cost if designed

Question

I would like to know the average production cost for the following,

1- microcontroller to control

- wifi module(esp8266)

- 5v relay(5v controlling 220v)

- I2C

2- ARM(armv6/v7/v8) SBC

- wifi or optionally (wifi + bluetooth 4)

- I2C

- GSM (3G TCP/UDP)

- RS485

- RS232

Thank you,

Check out ESP-WROOM-32 or ESP32. Might just need an opto-isolated relay and a power supply....(and some software)

Your question can't be answered without you providing a lot more detail - like how many would be a start. You can do some searching (Google will help) for similar boards or products containing similar boards and see how much they cost to get a feel for the price levels. Or you can pay someone to do the work for you, but they will start by asking you to answer lots of questions to pin down the specification. MK

amrrahmy I would agree with dougw , for #1 look at the ESP-WROOM-32 or ESP32. and for #2 Look at one of the RaspberryPi SBC boards perhaps.
