Backyard Vertical Vegetable Garden Wall Installation

We are planning to convert an unused 3.5-meter run along our backyard fence into a freestanding vertical vegetable garden wall and need an experienced installer to handle the full build. The structure will carry multiple tiers of soil-filled planting pockets, so the load calculation for the support posts and frame is critical — we want engineered footings set below frost depth, pressure-rated crossbeams, and a bracing pattern that keeps the wall rigid under saturated soil weight after heavy rain. The layout should stagger planting pockets and integrate a climbing trellis section for vining crops like beans and cucumbers, with wider lower tiers for root vegetables and narrower upper tiers for herbs and leafy greens. Please plan a drip-line irrigation loop with a pressure-compensating emitter at every pocket, a filtered hose-bib connection, and a simple timer so watering doesn't depend on us being home. Orientation matters — the wall should face to capture the most southern sun exposure available on the lot while leaving an access path behind for maintenance. All materials need to be weatherproof: galvanized or powder-coated steel framing, rot-resistant lumber or composite panels, and UV-stable liner fabric behind the soil pockets so nothing degrades within a season. We'd like a realistic build timeline from footing excavation through planting-ready handoff, plus a maintenance note on refilling soil and cleaning emitters. Send examples of similar tiered installations, your framing approach, and a materials list with the proposal.
