Dear Ladies and Gentlemen,
your project offer sounds very interesting. Actually I have just finished a project for a device that is quite similar to yours. It is slightly larger I guess. The device was a gastight design plastic housing that contained several mechanical parts, DC motors, PCBs and an optical sensor. I also hold a patent for an optical sensor for winding up thread on a bobbin, which will be of advantage when designing a mechanism to wind up and measure the fishing rod. I am an expert mechanical engineer and work with reliable partners for the PCB development. The bid I placed is a rough quote and we should talk about what state the prototype should have you want me to build. I am looking forward hearing from you.
