I want a website, that has about 20,000 user manuals for electronics (PDF Format) in a folder (i provide all the manuals in PDF. I want a website that will allow visitors to download the manuals (1 at time, so they don't use up all the bandwidth). The site should automatically produce a sample image of the PDF, begore downloading. Just like on the website below.

If possible, it should pull the first 100 words, to aid in search engine results.

I have a listing of 1200 manufacturers, and each one should have it's own page on my website. I won't give any information, except it have a Google search bar along with the Manufacturers name. I want you to create the website, logo, etc. to the best of your ability, in 5 days or less. There may be a free public script that does most of this.
