Need embedded systems engineer for designing schematic and PCB from a prototype.

We need help in creating a schematic of an Arduino based prototype we are working on. The micro-controller communicates through a GSM Module with backup WiFi Module. Other components involved in the process are a RTC Module, a memory card module, Battery charging module, a push button, loss of power detection module, 6 external modules using headphone jack and 1 external module via RJ45 i.e approximately 24 digital pins will be required. A mini/micro USB port for DC power input and also to program the microcontroller.

6 external modules exist as a separate boards and are connected to the main board via 3 pin headphone jacks. (Gnd, 5V and Digital Pin) i.e 6 connections.

Similarly another external module also exists outside the main board as a separate board and are connected to the main board via RJ45 connection. (Gnd, 5-32V and 6 Digital Pins) i.e 1 connection.
