Lead finder cloud based service

Technical specification. The core: This Facebook based service is providing opportunities for marketers, business owners any other people who is looking for prospects to find the leads on Facebook who are already searching for any specific service or product. The Service must help people to find public posts on Facebook that contain keywords needed. How will it work? For example, user of our platform is a web developer and he wants to find potential clients, he just needs to type «need a website developer» and push the button «search» . The platform shows up messages and profiles of people who posted messages on groups or profiles, as a result you see the whole message, it can be like «Please, help me to find a good web developer for our new website, I need contacts». To be showed up message should contain all keywords of phrase that he or she searched for. Once user types 3 or 5 keywords the platform will show all messages separately. Because you can search for «web developer» and «grocery store owner» they shouldn`t be mixed.
