Build a Website

Hi Need to build Voucher system management. There is a rough idea only so all suggestions are welcome. All system needs to sell Vouchers for small company who's giving a flight lessons. Example below: 1 Hour Airplane Flying Lesson 2 Hour Airplane Flying Lesson 3 Hour Airplane Flying Lesson 4 Hour Airplane Flying Lesson 30 Minute Airplane Flying Lesson 40 minute B737-800 NG Flight Simulator 60 minute B737-800 NG Flight Simulator Aerobatic Airplane Flying Voucher 40 minutes Admin needs to control how many vouchers is sold. Who bought it and what is the number of the voucher. Also the admin should Add new vouchers and remove them. User should have a chance to register to the system then buy a voucher and have ability to print it out. Track his purchases, and have ability to communicate with the admin through messages. Check if the voucher is still valid etc. Design and development expectation: - Design needs to match customer website (colours etc) - Modern responsive design (this is noce design [login to view URL]) - Database for storing vouchers it the backup/restore option - Front end dashboard for admin and users. Please attach official proposal to your offer. I'm available to talk on upwork messenger and Google Hangouts. If you have any more suggestion please feel free to put them into proposal. I'm expecting all done from A-Z. Please feel free to give me your estimations.
