Training data for sentiment analysis

Question

Where can I get a corpus of documents that have already been classified as positive/negative for sentiment in the corporate domain? I want a large corpus of documents that provide reviews for companies, like reviews of companies provided by analysts and media.

I find corpora that have reviews of products and movies. Is there a corpus for the business domain including reviews of companies, that match the language of business?
