We spend ~$8k/page on content development. Several hundred hours of investment per page (doctors, PhDs, nurses...)
I would contact Google via Webmaster Tools myself. It might never get read, but it sounds to me like your site is the sort of false positive that Google SHOULD know about. $8K per page sounds like the very definition of authority content to me.
If your pages don't rank well and used to then there is something wrong with the new algorithm. Google doesn't owe you a living, but it does owe its users the best results.
