Data mining on a specific website

It's a french online "yellow pages" but only with companies who are dealing in 'green energy'. We need: name, street + nr, place, postal code, tel. number, fax number, e-mail, website, category Website: [login to view URL] at the top right of the website you can see there are 4 categories: Quali Sol Quali PV Quali Bois Quali Pac I think the fastest and best way to search on results for this website is by searching on postal codes. [login to view URL] here you can enter a postal code and then you get to see all companies of all categories who belong to that postal code. Example: postal code: 80100 We get to see a list of all companies with place name + distcance from the postal code you entered. You can also see to which category/categories they belong. when you click on 'voir mon site' (translated = look at my site) and then you get to see contact details of the company. What you don't get to see is the e-mailaddress. I'm afraid we have to o an extra search on the url's of the websites we can find for mailaddresses.
