planting my hillside vineyard

I am looking for a landscape designer for my backyard hill in Concord California. The hillside area is approximately .5 acre. I have a small vineyard of 100 plants planted in the center and would like to plant natives along the perimeter to help keep the weeds down. I don't want to attract additional bees as they already are enjoying my grapes.

Any help appreciated.

ThanksCathy</p>
