Mr. Taraz, thinking loud here, isn't it less expensive? hiring a person to design the landscaping for you and then you take care of it step by step with the mock-up plan as a weekend experience, estiy sure it will be fun. This is how we did it on our terrace and every time we can we do something new or change something that we don't like anymore. Happy dreams
It is less expensive to do the planning myself - but it is still very expensive to get the equipment and materials here.
I wish that every stage of your garden is one of enjoyment and fun, for sure Smallsteps will participate and have fun taking care of the planting, the pruning, and so your emotional life will grow, as grows what you can harvest later with your parents. I will be watching for progress, on your project.
