Need help finding load cell, order qty would be > 32,000 units

I work for a large company that is interested in using load cells to help solve one of our problems. Order qty would exceed 32,000 units. I have been searching for a load cell that meets the below parameters but haven't been able to find a source yet.
Parameters:
 IP67+ (hermetic seal preferred)
 Operable up to 85 Celsius
 Range: 1020kg
 bending beam or shear beam
 cost: < $100/unit
 output: I2C preferred, analog fine if not
 preference: manufacturer offers calibration services
I realize $100 is extremely cheap considering the parameters I provided, but it's what we need considering the order qty. I have been looking for weeks to no avail. At this point I'd even offer a decentlysized cash reward to anyone who can help me find it. Thanks in advance!!
