I want a car search engine program that should parse/crawl 2-3 websites with cars for sale. It should run on an server and display the search results on the computer of the client in any browser (like a webapp).
How it should work: the client enters the characteristics of the car/cars he is looking for in the webapp and the program starts to crawl the websites for ads matching clients criteria. Once every 10 sec or so. When it finds a car that matches the criteria it should announce the client via the webapp opened in the browser and via the iPhone or Android mobile app.
The clients will have to pay a membership fee monthly via the webapp. It must also have a 3 days free trial.
The websites are [url removed, login to view] and [url removed, login to view]
The program will parse/crawl only the ads with cars for sale
