Platform that connects Startups and Investors

Description: I would like to develop a platform where founders/startups can basically write their startup's diary (from concept development to first prototype to first customer to first sale). The startup has a profile that shares all the relevant information a potential investor would be interested in. When the startup has reached a certain size it is ready to raise money in order to grow. The startup creates a pitch where the communitie's investors stand ready to ask questions about the business and/or invest in the startup. It's a site similar to [login to view URL] but the focus is on the startup and the startup's history and progress from concept-startup to ready-to-be-invested-startup. Requirements: * Website only * Multisided platform: - One login for startups/founders, one login for investors - Startups can provide basic information about the company (description, #founders/employees,) as well os continously add news (new employee hired, prototype developed, partnership with contractor, first customer, first sale etc.) - Investors can provide their experience (previously invested companies, which stage of investment etc.) * Admin rights - I, admin, can accept startups and investors to the platform * Technology: - Whatever you're most comfortable with. It should should support max 500 users (startups and investors combined) Please provide expected time and cost estimates.. Feel free to ask questions. Thx, Saud
