Help sending digital radios to Ukraine

Hi, my name is Alex and I am a communications technologist. My colleagues and I managed to salvage almost 300 digital radios that have been used on construction projects. About a hundred have already been shipped to a Charitable Foundation (Registration number 44816139 ) in Ukraine. Currently, a group of volunteers got 170 preprogrammed radios ready for shipping. Over 500 kilograms. Shipping receipts will be provided. I am looking for help to offset the cost of shipping. Reliable and encrypted communication is key to saving lives.
