Find information about hotels and enter it in a Wiki Media s

This is for a new project of mine, the job involves: :- Creating pages in Wiki software (mediawiki, which is run on Wikipedia type web sites) Approximately 30,000 cities are to be covered. Some of the work has already been done. Basically you have to search for the cities and put that in the site. :- Search for hotels and list them in city pages on the site the second step is to search for hotels and then put the hotel information (name, adress, phone no and website if any) on the page. It can have 10-100 hotels every city depending on various factors. but on an average let's say 20 hotels on one city page 200*30,000 = 600,000 hotels details to be copied pasted from the internet. - People with experience with mediawiki preffered.
