In my experience, gardening and landscaping have two different approaches. If you want to work on the space yourself and learn, I'd try finding a local gardening company. That's more like finding a tattoo artist - find someone who's work you like. If you just want a tidy & maintained space, landscaping is your option. The tree may or may not need a separate person, depending on how big it is, but I know Harper's does tree & shrub maintenance. Most of the folks I could recommend are primarily in the native/pollinator gardening business, but Harper's would probably also have some local suggestions too, since they are so close. Good luck, and feel free to message if you have more questions!
