I contacted a couple of houses advertising same day or 24 hr turn. They all told me that it would be difficult or impossible to do it in that time frame. Could someone enlighten me on what are reasonable quick(est) turns for various board technologies?

Not all boards (six layers in this case) are created equal. There are many things that a board manufacturer can do, but time becomes a very limiting constraint. Delivery time is very dependent on the panel design and attribute, line, space, hole size, pad to hole ratio, blind/buried via, gold, nickel, material types, hole quantity, scoring, milling,etc. Obviously the boards must be good when shipped, but often time does not allow some of the normal systems to be used. These systems would include electrical test, CAM design rule checks, netlist compares etc.. The board manufacturer would basically build the product per the data exactly as supplied, the customer should therefore have confidence in the data supplied to the manufacturer and accept responsibility for any design related errors. There is also a vast difference it data types, some much easier to use than others. It is amazing how large and difficult data can be dependent on how the features are drawn. There is not enough supplied information to determine true build time. I would recommend that you develop a partnership with your prefered supplier(s), each knowing what to expect from the other, no surprises. This will give you the best results. You have to understand the needs of the manufacturer, and he must understand yours. I can understand the reluctance of suppliers if you are a new customer for them. Please call if you would like to discuss this.
