Hello @lozmg76
To make your QloApps website work as an OTA you only need to purchase and install QloApps Marketplace.
More info here: https://qloapps.com/marketplace/
But to modify the search in order to search on the basis of location and dates and then list hotels on the search result page, we will need to customize the system.
