To avoid a lack of updates for software bugs, let's require that the scales model is either (1) currently in production, (2) supported by a manufacturer's software for their whole range of models or (3) supported by a third-party, open source software that is ideally in current development.
Within these requirements, I found:

Make your own using Raspberry Pi with GSM module, battery and additional software to track it. This is the hard way.
"Car" trackers can be actually used for other purposes. This $199 device looks good
but there's also a way cheaper alternatives that costs only $24.95
3. Two Phones method. Basically all you need to do is just to turn on GPS on the ...
Well yes, but actually no
From a software standpoint, I personally think the polish for Bluetooth location trackers has reached a point that it can be considered mature enough for "everyday" use. I personally don't have a ton of experience with them, but from what I have done and do know, they're in a good place.

I am answering my own question, in case it is of any interest to others.
For development, I have found an excellent and extremely cheap solution. In fact, it could probably be used in non-profits. Only for a commercial product would I need to have something custom manufactured, as I can't find a COTS solution (needs to be smaller, more rugged, with a ...
Not too rough, if you don't mind ordering from China. Check out this ELP-USBFHD01M-L36-120FPS on ebay. It's unbranded, but I've given you the model number so you can find it elsewhere. Currently, the cheapest place I can find is ebay, but that could change, as per comments.
It actually sports a Full HD CMOS USB Camera, which shoots at 30 / 60 / 120 FPS. ...
So far I've only found one VR headset which features inside-out positional tracking and does not require connecting to a desktop computer: the Occipital Bridge. It's $399, only works with iPhone 6 or later running on iOS 9 or later, and is capable of both virtual reality and mixed reality. It ships in March but is available for pre-order now.
I have years of experience with GSM GPS trackers.

There are few things that affect the devices you would need.
So place let me know answers to these few questions.
First you should decide what kind of protocol you would like to have ?
