I would like to hire a PCB Designer_2

I currently assemble my PCB with components in house, and am looking to shrink the size of my PCB board. I currently use a custom designed PCB board (using Fritzing software), Arduino Pro Mini 5V 16MHz, Bluetooth HC-05, Pololu's Mini Pushbutton Power Switch with Reverse Voltage Protection, Sound Sensor with Adjustable Gain, On/Off push button, Micro USB adapter, On indicator LED, capacitors and resistors. The board has been built and tested. Arduino's are open source and can be built using individual components. I do not have the expertise in Electrical Engineering. I used the Arduino Pro Mini because it came fully functional and ready to go. Now that I know my assembly works, I would like to build the smallest PCB board possible, using only the components I absolutely need. Similar to Project ID: 18533465
