Greetings sir
We are a product design agency, we did read the information that you provide in the description regarding the Vape industry and the product itself, so let kindly me explain you how this projects are carried out.
The first step is to make a deep research in the market an put things explicit, so we can have the proper understand of it and then formulate a value proposal for the design of a new product.
Then, once that defined, we move forward with the conceptual design, that's to create a conceptual model of what will be the product, this phase have two purpose, serve as an initial phase to give form to the product and will be the set of instruction to develop the detailed engineering. After this others phase comes, I can explain you more in detail through the chat.
For this bid, I'll quote you the first two steps the product research and the conceptual design.
Please let me know any questions that you may have.
Kind regards
