We are an industrial supply company servicing North America, looking to expand into water purification, specifically, deionizing. We want to provide DI units for spotless water rinses, for windows, cars, etc.

For this, we need a compact, battery operated device that can function while wet. We need an indicator light for the battery and TDS levels, and most uniquely, we want to be able to set up a wireless alert to the customer's phone, when their TDS levels are too high. This will let the customer know they need to change their filter media.

Nothing on the market currently has the ability to reach out to a customer's phone wirelessly, remain battery operated, compact, and have preset alerts.

Whether by one freelancer, a team, or a collaboration of skills, we are interested in paying well for the design, and perhaps future designs, as we would be producing these in bulk. Skills required would likely be a familiarity with electronics, engineering, and perhaps Bluetooth/wireless technology.

Please let us know what your experiences are, your expectations for the unit, and your usual fees.
