build a web scraper/crawler macro

I need a scraper to extract data from a website. The Macro should be able to be done on a weekly basis. The scraper will be executed from time to time from a computer with Mac OS X 10.7.5 and the product should be a Numbers file preferably (or can convert from Excel into numbers). The website is [login to view URL] It must include the first 3 defendants names, property address, parcel number, case number, date filed, and date that defendants must reply by. I prefer that the scraper won't require installing special software. Brief audio or FaceTime interview required along with examples of prior Macro's written for similar jobs. A screen shot of the website is attached below.
