Chinese (?) 4-panel screen with bold pines and peacocks

This is a 4-panel, 34.75" H x 59"W paint-on-paper screen.  It has a fabric mat and back over wood (I presume).  There is writing in two sizes and 2 chops in the upper right corner.  I know nothing about it, other than that it's bold and stunning.  It came from an estate on the East Coast of the US, probably from the mid-Atlantic states, possibly Maryland's Eastern Shore.  Is the artist known?  Is this from a recognized era or school?  What do the words translate to and mean with regards to the peacocks?  Does it have a value for insurance purposes?  Is it worth repairing the water damage and the lifting paper, and how would I find a conservator?  

Thanks for anything you can tell me.
