I am an Electrical Engineer and able to design PCB Layout via some design tool. Standard Layout of about 20 components about 100$.
PCB Layout in image format like .jpeg, .jpg, or .png would be provided, which might be used in printing the Layout on the copper PCB and then being able to make a PCB of your own choice.
Circuit Diagram design subject to given parameters. The Circuit diagram would be converted to Schematic via some electronic circuit design and simulation.
PCB Prototyping. If the PCB Layout is given and components are not that expensive and not too complex design is required. This depends upon the availability of the components and the complexity of the circuit.
