Until and unless you mention which body panel you need to press, it is difficult to say how much it will cost you.
For example
Door inner for CAR body panel may require following dies
1 - Blank Die
2 - Draw Die
3 - Trim Die
4 - Restrike Die
5 - Pierce Die
6 - hemming Die
Die number 3 -5 May contain other operations like
Flange , Plunge , Pierce operations in them
For producing big panels like Body side , Crash member, Floor , Rear Qtr. panel. you require complex design
If you can give the details of panels and some ref. pics
It will be possible to estimate the cost.
