Website Contract

Hi, I am a software engineer and work alone. I am planning to open up and website which will be used to collect payments from accommodation hotels for their bookings. Key: X is the Customer who wants to book a room in Hotel Y. Y is the Hotel Y who gives rooms on rent for Customer X. Z is myself/my website which would be used to make payment. I would be the online aggregator who takes a commission from Hotel Y for every booking. Basically the Customer X goes to Hotel Y's website and is redirected to my Website Z for payments. The Hotel Y gets the payment from Customer X through my Website Z. Payment gateway account is linked to Hotel Y' account, but to the customer my website Y is the payment collector. After the Customer X books the room, I will then collect the commission payments every 15 days through NEFT/Cheque from Hotel Y. I am willing to pay any taxes (if applicable). Now I (Mr. Z) would need to have a Contract with The Hotel Y. Also I need to tell the Customer X about the terms and conditions, specially the part that the payments go to the Hotel Y directly and I am just a medium. Please note I am just a normal person and not a company. Can I have such contracts with the Hotel Y? Can I tell the Customer X about the terms and conditions? How can I be safe for legal liabilities from Hotel Y? How can I be safe for legal liabilities from Customer X? I believe in startupindia concept but I would like to start small as a individual. Please guide me with this. Thanking you in advance.
