circuit board layout

We are looking for a talented individual to create a Super cap charger circuit board layout for us. We want to take our current external 4xAA battery pack which contains a USB port and on/off switch and replace it with a super cap (maybe a 5VDC Super cap ) charger directly connected to a 5V product that currently plugs into the USB port. The super cap needs to have a USB charge port and an on/off switch to turn the cooler fan on and off. The size of the board can only be 32 mm x 57 mm and height of 16.5 mm with just the leads to the 5V product and it should incorporate a combination of both through-hole components (on/off switch on bottom side of circuit board) and surface-mount devices (USB female port for charging super cap). We are open to suggestions when it comes to the layout design, and we are expecting creative input from whoever I choose to work with. If you have experience in circuit board layouts and are confident in your ability to design something that fits my requirements, please don’t hesitate to reach out. Looking forward to hearing from you soon!
