We've been sharing "our secrets" for years on this forum.
All you have to do to learn them is to make the effort to find and read them, which is easy.
Look up subjects under "Topics" or do a key word search.
There have been very long and detailed discussions of all aspects of pricing, advertising, signmaking techniques, etc.
Once you have made the effort to familiarize yourself with what has already been posted, come back and ask the questions that haven't already been asked and answered.
