We need an image of an old fashioned beam balance

We need a finely detailed image. we want an old fashioned scale - they usually have two pans, one on each side, so that weights can be placed on one side and herbs spices etc on the other. however we want THREE pans in a triangular configuration (I will try to do a sketch of this to illustrate what we mean). this image needs to be free standing so we can cut it out and place against different backgrounds. The scale should be modeled to give it depth and substance - a dull bronze - metallic -sheen would be nice. if you want to bid for this job we will ask for a quick sketch of what you plan to do and we will choose the provider who comes closest to our vision. i will be available all the time to answer questions as you go along..We are paying well because we want the best possible image.
