I wish you good luck.
What you want is a lifetime's commercial and technical knowledge and experience for free.
You can buy or subscribe to Conklin & de Decker (expensive) and even then you wouldn't have all the knowledge you are looking for as their costs are actually not always accurate.
The questions you don't ask show that anyone who takes your advice should do so with a pinch of salt.
Sorry, you just can't get what you want from a 3 line message on a website.
