Why do you think that those should be free? They're made of complicated machines. Someone has to get the metal (resources, but some of the metal might be rare) and make the 6 foot tall watch (lots of gold). They would need constant repairs and maintenaince (upkeep). Illusions and spiders on the other hand dont seem like they'd draw a salary, of course like you said it could repepresent the summoning costs and so forth.
