Unreal Engine 5 MetaHuman specialist: fix a build blocker and finish our virtual fitness instructor

Hi, I run THE BEAST GYM, an immersive fitness studio in Lawrence, Massachusetts, USA. Our training room projects life-size content on three walls. I have been building a virtual MetaHuman instructor for our gym myself, and I am stuck at one specific point — I need a specialist to take it from exactly there. Please read the full post before proposing: I am not starting from zero. WHERE I AM (already done, on my own PC) - I have an Unreal Engine 5.8.4 project ("MUNECABEAST") on my Windows PC (i9-12900KF, 32 GB RAM, RTX 3080 Ti, 2 TB SSD). - MetaHuman Creator plugin + full Optional Content installed (all official presets available). - My character already exists in the project as a MetaHuman Character asset ("Rubi") — identity created and saved. - Her "brain" (dialogues, functions, gym data) is already written on my side — that is NOT part of your work. WHERE I AM STUCK (the exact blocker) - In this project, the MetaHuman Character will not build. Through the MetaHuman Creator subsystem (Python API), can_build_meta_human returns False and assemble_for_preview returns None — before and after adding the character to an editing session — both in a headless commandlet AND in the full GUI editor left open ~48 minutes to settle. - The same happens with a clean duplicate of an official preset (Ada), so it is not my character's data — it looks project/environment-level. - Result: the build never runs and no skeletal mesh, body or face assets are ever generated. The project still contains only the 2 character assets. - I cannot get past this point, which is why I am looking for a specialist. WHAT I NEED FROM YOU 1) First, diagnose why this project/environment refuses to build MetaHumans and get my existing character "Rubi" to build properly in MY project, on MY PC. If you prefer to rebuild the character cleanly inside my project instead, that is fine too — what matters is a built, working MetaHuman in my project that I own and can keep adapting. 2) Then complete the rest of the scope: - ROUTINE LIBRARY: she performs fitness routines retargeted from plain videos I supply (spinning, functional training, mini-trampoline jump, no-contact shadow boxing, and dance fitness), with a repeatable pipeline so a new video becomes a new routine. - PRESENTER / ANNOUNCEMENT MODE (very important for us): I type an announcement text and she speaks it on camera with accurate lip sync — Spanish first, some English — and the result can be exported as an MP4 video file for Instagram ads and our gym screens. - VOICE AND PHRASES: Spanish-first local TTS voice. She greets gym members BY NAME from a list I provide, with phrases I can update and train later without a programmer. - She must run LOCALLY and OFFLINE on my PC. No monthly subscriptions and no cloud dependency for daily use — one-time payment only. - Please also confirm whether these are included or priced separately: mirror mode / form correction using our Azure Kinect DK sensor (we already own it), and triggering routines from our system via simple OSC/JSON events. 3) FULL OWNERSHIP — NON-NEGOTIABLE: complete Unreal project source files, all accounts/licenses in my name (THE BEAST GYM), and a recorded step-by-step tutorial showing how I add a new routine from a plain instructor video and update playlists and voice phrases without needing a programmer. No black boxes, nothing locked to your accounts. MY QUESTIONS (answer them in your proposal) 1. How much do you charge to take it FROM THIS EXACT POINT — first fix the build blocker in my existing project, then complete the scope above? Give me your fixed TOTAL price for starting here, not from zero. My total budget cap is USD 1,000, one-time. 2. What is the delivery time? 3. What exactly do you need from me to start (logo files, routine videos, sample announcement texts)? Before I fund anything, I need two things in writing here on Upwork: - An ITEMIZED LIST of everything your price includes — feature by feature — and a separate list of what is NOT included or costs extra. - Your written confirmation that after delivery I can keep adapting her myself (add new routines from videos, new announcement texts, new greeting phrases) without hiring you again, using only the tutorial and tools you deliver. If any of my uses above is NOT covered, say so plainly in your list. I will only fund the escrow after the full scope and the fixed price are confirmed in writing here on Upwork.
