Need an experienced developer to build a full desktop companion app for Toontown Rewritten

I need a full-featured desktop companion for Toontown Rewritten that runs on Windows and is written in C++ with an ImGui overlay. The app must attach to the game process, read live memory (enemy HP & level plus my current gag inventory) without resorting to OCR, and then use the lookup table I will supply to calculate the best gag combinations every turn. Those recommendations have to be rendered in a smooth in-game overlay that updates in real time and never blocks normal gameplay.

Core scope
• Robust, pointer-based memory reader that copes with dynamic offsets and different game builds
• Calculation engine that consumes the provided CSV/JSON lookup table and outputs the optimal move set in <50 ms per tick
• ImGui overlay injected or otherwise layered so it can be toggled on/off, scaled, and themed to match the sample mock-ups in the attachment
• Clean installer or portable build, plus full source with comments so I can maintain offsets later

Acceptance criteria
1. Launching the tool with the game running shows correct enemy HP, level, and my gag counts within two seconds.
2. Recommended gags update instantly when inventory or target changes.
3. Overlay stays fixed at 120 FPS (or vsync) with no measurable frame drop in the game.
4. Source builds in one step using CMake/MSVC 2022.

I’ve included a PDF with memory addresses, a demo overlay video, and the full lookup table; feel free to suggest improvements, but please outline any additional tooling you’ll use (e.g., Cheat Engine for scanning, DirectX hooks, Detours, etc.) in your bid.
