PCB for Trailer Light Tester

I am in need of a PCB design for a trailer light tester. The design required is a single-sided PCB, with dimensions within a specific size range. The components to be used in the tester will be a mix of standard and custom components. Ideal skills and experience for this job include: - PCB design experience - Knowledge of single-sided PCBs - Understanding of component selection and integration - Ability to work within size constraints Functions of PCB Power in (FIgure A) (12V DC Rechargeable Battery) POWER OUT - Battery Level Indicator (Figure B) The battery level indicator will be monitoring the battery power and will display this on three LED lights. 100%-60% (green), 59%-30% (yellow), 29%-10% (red) - Left Switch (Figure C) When switch is pressed, send power out, and if the circuit is good, display this by turning on a green LED, Also display battery level when switch is pressed - Right Switch (Figure D) When switch is pressed, send power out, and if the circuit is good, display this by turning on a green LED, Also display battery level when switch is pressed - Running Switch (Figure E) When switch is pressed, send power out, and if the circuit is good, display this by turning on a green LED, Also display battery level when switch is pressed - Ground (Figure F) (Neutral) - Mounting hole (Figure G) Size Requirements: The size of the PCB is really flexible, the mounting holes I would like to be 0.116 in. in diameter and on opposite corners of a 1 in. by 1 in. square. The placement of these holes is flexible as well, just let me know if they need to be moved. I have attached pictures showing where I'd ideally like the wires and mounting holes. In each up closer view of each figure I have the wire length and color listed
