Explanation:

they need outlines before they actually make them so that they wont mess up or so that if the customer does not like it they can fix it.

there is not really a certain expensive film type but i believe all of them cost mostly the same price, i hope this a little bit

relief sculpture - images are set against a flat background.

a coin is a good example: the inscription, the date, and the figure are slightly raised above a flat surface. the ancient egyptians sometimes carved figures into a flat surface.  

pro: they take significantly less time to make and do not require as much tools or skills as free-standing

cons: not nearly as realistic, as it is not fully 3-d, and does not have the details that a free-standing one does.

freestanding sculptures (also called  carved in the round) are not attached to any  background.   they are 3-dimensional  and fully rendered.
