I have a quick question regarding pattern making:

I'm trying to start up a small manufacturing company that makes bags for consumer electronics (ipods, laptops, etc.) and am meeting with some seamstresses next week in order to get some prototypes made.

How much is a fair price to offer for pattern making and sewing the prototypes? The people I'm meeting with are recent college graduates from fashion programs and have experience with pattern making and sewing, but aren't established professionals.

Thank you much.
