Did you just request the attention of a private tutor?

Private chatting means that no other people may gain anything from the discussion.

But that is fine. What you are looking for is commonly known as consultants. They can help you, for a suitable fee. How much where you thinking about paying per hour?

By the way - even a consultant would fail to make the Keil compiler into a C++ compiler. Maybe if you chip in a lot (!) of money, you may get Keil to consider rewriting their compiler to support the C++ language too. But I wouldn't bet on it.
