How to start wholesaling business

Im a new investor, I have read several books and articles and decided that with my current situation the best way to get started is to get into wholesaling and then buy and hold after I raise some capital…I have a few questions

                               1. What business entity do I use to structure my business.      
                                2. I only have 1k to start with so should I purchase a prices wholesale course first or should I make a few deals before I purchase one of the courses.

                                 3. How do you I market to build my buyers list

                                  4. Should I save my 1k to find a deal and after the first deal go through, establish my business structure.

I would appreciate any help anyone has to offer.
