I have a php based website where i want to add 3 features.
1. I want to add a hotel booking system using api (that i have already bought and will provide you with the api details)
2. Add a plane ticket booking system using api (i have also bought the api for this that i will provide)
3. I want to add a margin discount system. On my website users use service like Recharging there mobile phone or booking tickets. Admins can add users and can allow them a percentage (we call it margin). I want to make a system that if suppose admin have allowed a user a 5% margin then whenever this user will use any of the service he will automatically get a 5% discount at the time of payment.
