Scaled Garden Masterplan & Section Drawings – Rural Ireland

I have a half-acre rural garden in Ireland and a clear design concept already developed. The project includes:
* A 600mm sunken garden
* Earth berm for wind and privacy
* Timber yoga deck
* Orchard / meadow area
* Layered planting zones
* Wide limestone garden steps
I am not looking for concept design or styling.

I need:
* A scaled 2D masterplan (to scale, dimensioned)
* 1–2 section drawings showing existing and proposed levels
* Berm footprint and crest line clearly shown
* Sunken garden depth and finished floor levels
* Basic planting zones indicated
* Sightlines from hut level to the sunken garden
* Must show existing vs proposed levels clearly in section.

Applicant must be experiences in
* Site grading
* Section drawings
* Existing vs proposed levels
* Landform modelling (even simple)

These drawings are required for a landscaper to price and build from.

I will provide:
* Site photos
* Rough measurements
* Written concept
* Approximate dimensions

Experience with rural gardens, level changes, and drainage is important.
Please provide examples of previous technical garden plans (not just mood boards or 3D renders).
