CSV (or XML) to wordpress pages (or posts)

Hi I have a project which involves taking selected data from a csv or xml datafeed and adding that information to a wordpress post or page. I will try to give as much information as I can so that my request is fully understood. I have an affiliate relationship with an online hotel booking agency. They provide me with downloadable datafeeds in either csv or xml format. My site is focused on a particular holiday destination, so I am only interested hotels within that area. What I want to be able to do is create a wordpress post (or preferably a page) for specific hotels which contains information such as the hotel description, pictures, amenities, facilities etc (all of which is present in the feed) and display that information in an attractive and consistent way on every page I create. Within that page will be the relevant affiliate links containing my account id which will take visitors to the specific booking page for that hotel (which would be a branded external link). I am not necessarily looking for full automation; in other words a magic button that automatically creates hundreds of pages. That would be nice, but I have no objection to manually creating each page - but this process would have to be quick and easy. In other words, I create a new wordpress page; presumably selecting a specially created page template - and then I would want to simply add the specific hotel id for the hotel I am adding and then the relevant information be pulled from the feed/database and added to the page I have created ready for immediate publication. Ideally I would be looking for somebody who has done something similar in the past.
