Sites that pay? There aren't really sites that'll just pay you for submitting. There are a few different ways you can make money from your 100s of PLR articles:
1) You can sell them. Sell your PLR articles as a PLR package of some sort. Make sure you have Master Resale Rights (MRR) before doing this. You can sell them on this forum, on other forums or create your own PLR brand.
2) You can publish the articles on article directories. On each directory, have links pointing back to your site. Your site sells a product or promotes a CPA offer, thus making you money.
3) If you really want to make money by submitting articles, you need to have high quality original articles. Sites like BrightHub, Associated Content and others will pay you for your content. But they only accept really, really good stuff.
If you're just looking for a list of directories to submit to, a Google search will help you figure that out. Good luck!
