Which is the best software for creating 3D sustainable landscape designs on MacBook Pro?

I spent the last nine years trapped in an abusive marriage I wasn't allowed basic things like a computer although I did have an android phone for basic app stuff , my own life etc etc Not having any real computer access for that period of time has left me completely in the dark in regards to that kind of technology . So bare with me while I explain what exactly I'm looking for program wise .

Specifically I am looking for a program that allows me to take my sustainable landscape designs from a basic sketch to a completely finished full color scale 3D design so that clients can get a quality detailed look at what the finished job will look like on their property to sign off on . I am really good at blue prints to scale just need to figure out what the best program is to learn how to bring it to life for my business. Hopefully I explained that well enough and someone might have some helpful direction for me .
