Hello! To answer your questions, no, I don't have a crew that I work with. High Country Gardens does grow many of the plants in your design; however, because they are mail order, they ship only small size plants. That's fine for perennials, we don't need 5 gallon on those. But for larger sizes on the shrubs and succulents (which are typically slow growers, so we want to start bigger) Star and Moon are still the best bet. In my experience, plants may need to be sourced from more than one nursery. I'm happy to supervise in September to make sure everything is correct if you wish!
