I need a landscape designer or architect

I want a master plan of our yard before we start planting grass other plants, and start installing sprinkler systems. We just built and have a daylight basement that sits on an acre. The property needs some privacy as it sits on a hill for a subdivision to see us. I've attached a drawing I did to brainstorm the landscape layout but it's horrendous??. I've also attached a PDF of the the topography of the property, which has changed some but it gives you an idea of the lay of the land.
