Hotel Booking Online Portal

We are looking to start an online hotel booking portal for our international clients across the globe. Currently, we have multiple offices in Delhi and UK. We are opening a new office in UAE and need someone to help us build a new website, booking system and mobile app.

We need to have the flexibility to list our supplier's prices on the portal with a payment gateway linked to it. The portal will be used for various suppliers and the system should have the ability to create individual logins for these customers.
