Here is the assembly of a custom rain scuppers I fabricated to better give you an idea of what I can offer you

This was made for Robert L Alspaw of Advanced Gutter Systems for their client in Sacramento, California. It was designed for the rain-cups you see below. It has a large 3" x 4" corrugated copper elbow mounted backwards on the bottom to divert the water out to this set of rain-cups held by a stainless steel chain secured inside the scupper. Their wholesale cost was $325 + $40 for the stainless steel hardware I added in it to support the 2 story rain-cups. The chain is held in place with a pair of thick 48oz copper brackets bent over the top lip and riveted in place. He opted not to go with the internal liner I recommend to lower the cost.
