No wonder you can afford to attend CES 2018 when you are marketing what is essentially a simple product (i.e. BLE + LoRaWAN, not even a GPS) for $300-$ 500!! If I do a calculation of the component costs as shown on the datasheet I am pretty sure that it can be produced in quantities for less than $ 50, including housing.
Obviously you need a “commercial margin” but you might be aware that there are already many equivalent (and better, IMHO) out there that are a lot cheaper. Are you selling gateways as well?
Apart still from the technical issue how to shoehorn BLE data streams into a bandwidth and duty-cycle limited LoRaWAN channel, as BoRRoZ rightfully asked.
Good luck there in Las Vegas!
