Update 10/9/19:
Porsche agreed to split the cost with me (my car was out of warranty) so they just installed 2 new door panels and the cost was about $1100. They look great.
An alternative that I found out about on Planet 9 was Pedro Bonilla at PedrosGarage in Odessa Florida. He fixes these door panels in about 2 days and the cost is between $150-$250 per panel depending on the actual damage. They have been fixing these door panels since around 2007 (in the 987).
