Well Newart, my suggestion would be to sit back, drink a brew and get over it, seriously. My guess is that most of the forum members here have done something similar if not worse regardless of what they fess up to. Lord knows I've done much worse due to my stupidity, F'ing Up and age do have their benefits though........
My suggestion, find you local German (Porsche, Audi, BMW, etc,) dealer and cordially / honestly explain your situation and ask who they use to handle such repairs. It will help if you give them a sob story about whatever reason you cannot afford to pay to have it repaired conventionally, through in a stupid money repair you just paid for prior that you didn't see coming.
If THAT doesn't work, if you are anything like me you'd **** a brick at how wonderful the results are with some elbow grease and following the directions from the Dr. ColorChip, Paintscratch.com or whoever you choose. Make sure to shoot 2 to 3 coats of clear over the color extending into the surrounding paint.................
