We have been doing the do-it-yourself way but there are sites that can really assist with landscape design. I do think that it has to be your own design and creation and SLDA Landscape Design Associates can do the same by asking you what your preferences are. They can create exactly what your wants are so that it is functional and beautiful at the same time. If you do not know where to start, you may want to consider starting with them. They have a team of professionals that will work with your vision--not theirs--so that your completed landscaped yard will be a reflection of you.
You can chase a butterfly all over the field and never catch it. But if you sit quietly in the grass it will come and sit on your shoulder.
