I'll be glad for any help. For some more descriptions of the surroundings of the manor you can check the following thread. First three posts of mine are good for info mining.

As for the map - dunno about the sketch ratio but you can use it just as basic information. The manor and surrounding lands (lands that belong to the players) should be around 2400 acres (circa 3.75 square miles). Feel free to double the size and add a neighboring small village, a mountain, few ruins, etc. The area is currently mostly unexplored but the PCs know the major locations.

If there are any more questions, I'll gladly answer them.

And again, thanks!
