Hi, I'm looking for a US based EE to design and prototype and simple circuit with a 4 digit 7 segment LCD display, a hall-effect sensor, and a pushbutton. The circuit should have a footprint no larger than 90mm x 45mm x 12mm The basic operation is that clicking the button increments the count while the state of the hall effect sensor determines how the count is incremented. There is more detail than that, but those are the basics. Please quote both the development cost and ballpark cost and lead time for making 20 units. Final deliverables need to include layout files for production as well as all firmware.
