Fixing an existing schematic and lay out it- PCB Design

We have a small prototype circuit (~30 components) based on the ATtiny85 designed in KiCAD and prototyped using a Digispark. Major functionality is incoming power conversion (75v -> 5v), incoming voltage measurement, and current dump into a resistor network controlled by the ATtiny. Project scope is development of a BOM of SMD components based on the schematic and layout of a two-layer PCB. Scope could also include assembly and testing of the first few units as well if availability / skills permit. Ability to review the circuit design for errors or improvements is a plus. Experience with power conversion design using the TI LM5008 buck converter or similar would be appreciated

I will provide you more detiails
