Clear 1/2 acre of blackberry bushes....and then....plant ?

[John D.]

Hi All-

     I'm under contract on my first higher end flip, in Grass Valley CA.  Currently the majority of the 1/2 acre, the moderately sloping back yard, is covered in blackberry bushes, in some spots up to head height.  The backyard is about 1/4 acre.

    After I've cleared them, I'm trying to figure out what type of cost-effective ground cover or landscaping I can do, that will look good fast (45-60 days).  Is it realistic to think I can get grass from seed to look decent in that timeframe?

   Most of the homes in the area don't have larger proper lawns, but rather have a mix of tree and bushes with either planted grass or more often natural ground cover.  

   I'm just not sure what to do with what will likely be a very bare looking 1/4 acre of land after we rip all of the big thorny blackberry bushes out.

   We should close April 1 and thus would be cleared mid April.  In case you are curious, here's our local weather.  Slope is north-west so less then a full days sun.

Thoughts!??
