IOT Project with ESP32

I need the design and construction of the following 3 prototype cards (as smaller as possible):


It is based in this board: [login to view URL]

On that page there are video links where he explains in detail the functionalities

In his site he publish his electronic diagram and many details about it. But his design is based on ESP8266.I need a design based on ESP32.

This first board will have a header (8 to 10 female pins); here it be routered some signals os GPIOS, V+, GND,I2C,SPI. This header will be able to attach another board, like the image i'm insert.


This board will add the functionality to LORA 915 Mhz transmision. It will have a header with male pins, to be attached on top of Board_A


This board will be use attached (on top) to Board_A and contain the circuit for Adapter/Amplifier for temperature sensor PTT (like [login to view URL]), its electronic diagram is on internet. But this board only will be used with Board_A (when no LORA transmition stage is requeried). On other words only one board will be connected to Board_A, or B or C, no both at the same time.

First job I realy need urgent is about Board_A; but I need to know the cost of all the three boards.

Please, post your quotation about these items:

Job_1). PCB Design (Gerber files to send to China manufactures) of Board_A.

Job_2). Job_1 + Prototipe of Board_A (construction and test complete)

Job_3). PCB Design (Gerber files to send to China manufactures) of Board_B.

Job_4). Job_3 + Prototipe of Board_B (construction and test complete)

Job_5). PCB Design (Gerber files to send to China manufactures) of Board_C.

Job_6). Job_5 + Prototipe of Board_C (construction and test complete)

Must to indicate estimate days of complete each Job. I really need urgent Job_1 or Job_2.
