I've got a team of 20 developers working on software development and a team of 4 developers working in the field of embedded system. My company has been working on such projects since past 3 years. Elite clientele whom we have given solutions in embedded systems i.e. circuit design, microcontroller, its programming etc are Mahindra and Mahindra Ltd., LNTMHI. We've started applying on freelancing sites recently and hence have kept the bid at lower end. I can share our past work in case you are interested.
