10+ years experience in product design here. There is nothing about a “simple” product that is cheap or easy. Say you hire a design engineering firm to design it, who is going to make the parts? Have you ever worked with manufacturing in Asia? Who is going to assemble it? Who deals with the inevitable issues?
Then you have to think about selling it. What certifications do you have to get?
That is just hardware, now repeat many of these same questions for firmware and app development.
Now you have a product, what are the customers and who do you need to hire to market and sell to them? Assuming someone is interested in purchasing it how much money do you have to pay for all the product up front and warehouse it?
There is a damn good reason why so many Kickstarter projects never actually ship. Hardware is hard even if you know what you are doing.
Until I got to the specific shit I thought this was going to end with a punchline about Canada geese.
