Hotels site price comparison tool

I'm looking for an app that simply does this hosted on Linux server: 1) I enter a city name and date and it searches for all the hotels in the city on [login to view URL] for that check-in and check-out period. 2) It then goes ahead to compare the hotels found with [login to view URL] and [login to view URL], and lists their prices as comparison with Travala.com. The results can go into an .xlsx table (sample attached) 3) The matching will be done by exact Hotel_Name, if no exact match is found, that result is not displayed. 4) I can choose to enter multiple check-in and check-out periods, and so it will display all the results, starting from the first date. 5) There is a "minimum saving %" column, which equals: IF Travala price < (lower of [login to view URL] or [login to view URL] price), THEN Minimum Saving % = Travala price / (lower of Booking price and Expedia price) * 100 ELSE do not display Minimum saving % - - - Purpose of site is to check how much better Travala is compared to major travel booking sites. Not looking for fancy designs as this is just for myself. Hosted on my Linux web server. I am paying $100 AUD for this job. There may be further steps to develop this project in near future. Please check the attachment of sample.
