Looking for a supplier for Digital Postal Weighing scales

RFQ Details

I would like the scales to be accurate so that light objects can be weighed in both grams and ounces. At the same time they should also have the ability to weigh heavier items with a capacity of at least 5 kg. The scales should have a digital display displaying the weight in kg/lbs. The scales themselves should be quite light maximum 2 kgs so they are easily shippable. It would also be a bonus if the scales could also be programable so thet shipping costs can be calculated. Thanks
