Ken, here is a link to show you what a Flexible Shape Pattern is and how to make one.

If you are wanting to make 100 you need to develop a production forming set of dies and stamp them. This is very expensive to do and not something that we do often on this site. We mostly deal with making one or two identical item or a left hand and right hand panel.
Making a panel like that will be very time consuming if you do it by hand or very expensive if you have to make a set of die to stamp them. If you stamp them you need a very big expensive press.
What is the panel for, looks like an inner fender panel for something.
