I need a good Mobile App (Android, IOS, HTLM5 )developer to create for me a Bid Opportunities Listing & Bid Event Diary Booking app that will publish a list of 100s of lists for my subscribers. The purpose of the app is to make it easy to entrepreneurs to search, get notifications, select, add to diary and keep track of request for bids (or Tendering Opportunities) and their up coming briefing meetings and tender submission due dates. The app will provide entrepreneur with convenience and value adding logistical services like appointing freelance consultants as well as document collection and delivery. The app will have functionality, look and feel of an Event Booking & Calendar Updating system with Tickets and Delivery Service Ordering and Payment module. The opportunities and events must be organised and searchable by region, sector and requester. The App must be secure, fast, intuitive, appealing to browse thru and easy to use.
