I need a javascript website scrapped

I have a website behind a login (I have critical) which uses javascript to show the search results of around 90,000 entries.

I would like someone to scrape all 90k pages, grabbing a few data points from each page.

I will provide details of the site, and login details, to the chosen person before we agree on the job That way you can check it out first.

To apply, please give a rough ballpark quote and cite previous experience. I will then give the details to the best candiate(s).

I would like this done ASAP.
