-the website stands for a business brokerage portal whereto post details of various companies available to buy and sell
-the main website functionalities will be to allow buyers and sellers registrations, provide details of traded companies, provide details of M&A opportunities, etc
-the menus/submenus and website content will be customized according to our needs
-some reference sites will be provided upon request. They should be used as indication on how our website needs to look and operate
