Product and Circuit Design- Juul Case with Nicotine Tracking Functionality

Hello, I am looking to manufacture a case for the Juul that can track Nicotine consumption (how many times and for how long does the user smoke the Juul) and transfer this information to a smartphone via bluetooth. We are based out of California and are currently conducting some testing and feel like this could become a very popular product. Would you be interested/able to assist us in designing such a product? I would need a design and renders for the outer casing. Technical design of the circuit and how it would be able to track the time and frequency of the user smoking the Juul and identification of components that could potentially be sourced for the manufacturing of the product. Thank you, Chinmay Patel
