How should one go about manufacturing hardware wallet for masses. What should I need to know in terms of theory, team, production, cost etc.? Just point me to the right direction and I will try to learn by myself.

Your device won't be the first hardware wallet like Trezor used to be once so you need to offer something new (lower price, better features, more coins etc.) If you can't provide that, there is no need to create a new product. As on how to start, If you have enough programming knowledge (or at least, a small team with you) you could start and then seek investors for production etc.
