Someone in NYC to build a digital scale (paid)

I'm seeking a NYC-based tech enthusiast with previous experience building things with arduinos to make a digital scale using a load cell with a 1.5ft x 2.5ft platform that will weigh up to 25kg with a precision of 50g and connect to an android tablet.

You'll be paid for your time and materials.

Please email me if interested -

It is almost always better and cheaper to use an off-the-shelf device if one is available than to pay someone to devise and construct a prototype. Surely someone is selling digital scales?
