Design-build firm for retaining wall and landscaping?

We have a large retaining wall that's on its last legs that we need to rebuild with permits. We also want to do some other landscape related work in our backyard, like a deck addition, building planters and other less heavy duty items. Are there good firms out there that can handle both the design and construction aspects of all of these projects for us? We've had some work done on our house and I'm getting construction research/decision fatigue; would love to work with a reputable one stop shop for all these projects if one exists. Thanks for your advice and recommendations.
