Dear.
I have experience designing multiple PCB and schematics. I designed circuits with USB and Wi-Fi connection, PCBs with different types of sensors, i2C, SPI and others serials communications.
I can program the firmware that you need, and the PC / celular application. But, in the last case, the PC / celular application, I can only prepare the communication, variables, size of buffer, etc.
For a best quotation I need the next information:
Size of PCB that you pretend.
If you need all in SMD or through hole, or may be both.
Type of LCD (I assume 16x2 characters)
The layout that you pretend, if you have one. If don't y need more information about your requirements
For last, the consumption are defined by the components. If you have a requirements of the components, please let me know.
Please, if you need more information of quotation or other write me.
Best regards.
