Backyard Planter landscaping

Looking for an experienced landscaper to refresh our front and backyard with modern, minimalist and low-maintenance landscaping. Backyard: Two elevated concrete planter boxes (3m x 2m each) requiring removal of existing vegetation and replacement with attractive, low-maintenance plants and decorative charcoal pebbles. As the planters are raised and currently underutilised, we’re open to creative, cost-effective ideas to improve their appearance. The paved areas also require pressure washing. Front yard: A smaller, fully paved courtyard with no existing planter boxes. We’d like to introduce some greenery using modern freestanding planters, preferably charcoal, with minimal, low-maintenance planting. The design should complement the backyard, feel warm and inviting, and maintain clear access through the existing gates and doors. The job should include removal and disposal of existing vegetation and green waste. Please provide a quote including labour, plants, planters, materials and pressure washing of paved areas. Indicative inspiration photos attached. Open to suggestions and cost-effective alternatives.
