Yes we do. Rush Jobs are physically processed in the exact manner as Normal Jobs. This includes, but is not limited to, the same printers, investment and jewelers. Rush Jobs are placed to the front of the QC line, where they will be given priority in inspection. Rush Jobs will generally be invoiced and shipped one business day* ahead of Normal Jobs. Rush fee is $25
