Call your landscape company and discuss!
First, do your research, the best way to find a great contractor these days is through the website called Houzz.com. It provides a place for landscaping and other contracting companies to showcase their exceptional design and workmanship with high resolution photos and engaging customer reviews.
There are other websites that are review based but do not hone in on the type of workmanship you are looking for. Not every landscaping company is specialized in the type of work you are looking for. There are many Landscape contractors that focus only on retaining walls and grass for example or just interlock paver products but have no experience with plants. Houzz.com does a great job of showcasing landscape companies that are design oriented. That will help you through the design process and get you to a project that will meet your budget and accomplish your goal of a beautiful, functional, easy to maintain space where you’ll be comfortable inviting and entertaining guests.
