What is the process for printing bumper stickers?

Is it:

1)  Print

2)  Apply laminate?  This is the part I really wonder about since I assume I would need to put a protective layer over the print?

3)   Contour cut-can I do this by hand easily?  What cutters would work well for contour cutting bumper stickers and odd shapes?

4)  Apply backing and trim backing? 

Thank you!
