    I am looking for someone to design and assemble 10 PCB prototypes that are small in size and simple in complexity. The deadline for the project is 3-4 weeks. Unfortunately, I do not have all the necessary components and documentation ready, so I will need help sourcing them. I've attached a schematic for a board which works for what I need yet is too expensive and too large. I need someone who can use this schematic as a ground floor and design a similar board with newer components and better technology in order to make as follows: -- Size: Smallest footprint possible. -- Cost: Expense to be as low as possible per unit. -- Quality: Need these to be high quality. -- Reliability: Must have quality components so board can be used indefinitely with no failure. ...
