Dark-Fantasy Modular Environment for Unreal Engine

I need a modular environment asset pack for a game, a photorealistic colonial dark-fantasy game, matching the attached references.
The scope is individual pieces, including variations: trees, bushes, tents, banners, carriage/cart, barrels, crates, furniture, lanterns, books, rubble, fences, doors, stairs, pillars, walls, ground pieces, twisted roots, and decayed neoclassical ruin modules. Please provide an itemized list separating unique models from variants before finalizing the quote.
This is a one-time pack, with every asset reusable separately, plus a small assembled UE5 showcase scene demonstrating consistent scale, materials, and lighting.
Technical requirements:
- Engine: Unreal Engine 5.8.2, Windows PC.
- Nanite: Use where appropriate for detailed architecture and solid props; propose the foliage approach separately.
- Wind: Basic adjustable wind for foliage and banners. Quote player-reactive foliage separately as an optional extra.
- Textures: Generally 2K PBR, 1K for small props, and 4K where justified for large/hero assets. Shared materials and trim sheets where practical.
- LODs: LOD0 plus 2–3 reduced levels for non-Nanite assets where appropriate. Propose triangle budgets by asset category.
- Assembly: Real-world scale, grid-snapping architectural modules, sensible pivots, and simple collision.
- Performance: Support scalable settings for a game targeting 1080p/60 FPS on RTX 2060/RX 6600-class hardware.
Deliver editable source files, FBX exports, textures, and the organized UE5 project. Assets must be suitable for commercial game use. Please include pricing, timeline, revision allowance, and any exclusions.

If you made your proposal with AI, include that as the last line. If you have reviewed the attached photos/reference sheets, list how many windows are in the pack in your proposal.
