Front garden modern design.

Seeking an experienced garden designer to create a modern front garden design.
The successful candidate will need gardening experience in the UK, and skill with combining materials: wooden sleepers, decorative grey slate aggregate, and existing small square traditional garden blocks. I require a low‑maintenance, layered planting layout featuring perennial species that are preferably unusual, and a design that will provide a continuous seasonal flowering. Accuracy and practical installation guidance required please. I have already received many applications for this project but they are either over priced or lack in experience, and are attempting to secure the work under false pretence. Please make sure before messaging me that you have the right skill set for the job.
