It is a pain to remove, but possible. Look on YouTube for a 981 removal of engine cover. It’s the same except there are torques screws on the slide covers and 4 on the aluminum bar.
I guess that amount of labor is okay given how much they typically charge by the hour. For future jobs are you planning to stick with the dealer or find an independent shop?Spoke to a couple of mechanics at our dealership and they quoted that their hourly billing would be approximately 1.2 hours to remove the carpet panel so that I could permanently attach the Cayman badge. I'm reluctant to remove the surrounding clip-on components but will wait until the carpet needs to be removed for service, and then I'll permanently attach the badge. However, I did screw in two 8-32 screws in the badge, sharpened them with a file, drilled holes in the carpet, and inserted the screws into the carpet. Seems to hold o.k. for a temporary fix. I have a poor quality image of the badge in place, in case someone wants to duplicate. I received a lot of compliments on the badge at a German Marque showing this last weekend. Thanks for your help everyone./Users/tn4lee/Desktop/20170724_161309.jpg
