Angel.co App

We want to build an App to provide same the services by [login to view URL] [login to view URL] has 3 main user groups: Startups , Angel Investors, Candidates. They have a very good database design that helps to generate graph charts on the fly. They allow Investors to create syndicates to group many investors together before pumping in money into the Startups. At the same time they allow startups to hold fund raising. Please spend enough time to dig into how the fund raising is done online. We need an App to be done first base on [login to view URL] and leave room for future expansion so that we can add in more new kinds of user groups and services to interact with the first 3 main user groups. We want this App to be done in Multi-Language Platform detecting the smartphone / iPhone selected language. We need to have data import function so to fill up the App before we launch the app. As this App is for professional users, its must be butter smooth, flawlessly implemented. Please give me a price quote and lead-time. If reasonable I will discuss further with you on my other 2 app projects. Thanks Cyril
