I'm making a website for a small hotel in php. The hotel owners want a reservation system that uses paypal. They want people to see a calendar and choose a date to make a reservation. If the day has vacancy, they want the user to request booking a room. This would then require the hotel owner to accept the purchase.

I have not worked on a project that has this "request to purchase" method of buying with paypal. Is this possible? Does anyone know of an open php system that handles this?

THANKS :)
