Google has a section on their Site called GOOGLE "Answers". I have never run across it before.
Here is how it works:
1) Ask a question
2) Set your Price
3) Get Your Answer
They advertise that your questions will be answered by GOOGLE experts usually within 24hrs.
It seems that anyone can find out why they were banned, why the don't have better listings, why a Ranking Dropped and even why SERPS went South!
They also have a good database of questions answered for reference.
See for example: http://answers.google.com/answers/threadview?id=365893
Hope this helps the "lost",
