Here’s your situation.  You have a design on a breadboard or lab bench, which looks like a tangle of parts, fibre and wires and which may need someone hovering over it to keep it working.

I can:

• turn the design into a prototype
• turn the tangle of parts, fibre and wires into something tidy and robust
• put electronics and software around it to make it user-friendly
• put it in a box, so it will survive international shipping

I can’t:

• turn your tangle into a production-ready system in one go (it usually takes two or three iterations)
• make a silk purse from a sow’s ear (if the design concept has fundamental flaws, prototyping won’t fix them)
