Web parser keys from the site www.indiegala.com

Нужно to make the parser keys for the site .
An example of a page with parse information in the picture. Initially, the keys are hidden on the page and to display the key you need to press the button Steam.
The parser should provide a web page with a form where you enter the links (each link on a new line), a start button and a ProgressBar. On completion, you should output the file to download (Excel or cvs).
computer program I wrote and it works fine, now need a web page. Hosting and domain are available.
