I own a site that that has about 15,000 pages that need some description content.  I plan to hire someone to retrieve or create content for each of these pages on my site. each page needs about 500 words. I was thinking that there is probably three ways i can go about this. If I hire someone cheap I can probably have them copy data from about 20 different sites. using about 5 sources for each page description. I can hire someone that has some experience writing english content, and have them go to a few sites and then in their own words summarize the description on my site. I can hire a great content writer, have them do research on each page, and create completely unique content. I probably will do some combination of these 3 things. (great content writer on a few pages, since thats all i can afford to do) and the rest do the cheaper route. Is copying sentences from multiple sources a good idea? or does the content really need to be original?
