Yes, I acquire the materials and do the installation for the given project. Doing the acquisition selection and installation is part of the art of the design. On occasional projects I get subcontractors, or employ people I'm already familiar with, - whom I have covered with worker's compensation insurance. And of course, the owner and family are always welcome to work on the project too. Pre-landscaping demolition is available also, which is sometimes subcontracted out, and, you can help out with the demolition too if you like.
