Unity Developer Needed: High-Graphics Umrah & Hajj Training Simulation (Desktop)

About the project

I need an experienced Unity developer/team to rebuild a Hajj and Umrah training simulation as a high-graphics Windows desktop application (.exe). This is a non-commercial university project to help pilgrims learn the correct method of Umrah and Hajj. An older version already exists with all the basic functions, but the graphics are poor and the character movement has bugs (passing through walls, getting stuck). The main goal now is HIGH-QUALITY GRAPHICS with smooth, bug-free movement. WHAT NEEDS TO BE BUILT 1. Umrah module (first priority): third-person character walks inside Masjid al-Haram (WASD + mouse), sees dua windows near the Kaaba, performs 7 rounds of Tawaf with a round counter and key-press actions, prays 2 Nafl, then completes 7 laps of Sa'i between Safa and Marwa (faster walking in the green zone), with duas and audio guidance. 2. Hajj module: Mina, Arafat, Masjid Namirah, Muzdalifah, Jamarat (pebble throwing) and Masjid al-Haram, with short animated travel scenes. 3. Masjid an-Nabawi: free-roam walk inside the mosque. 4. Short animated intro video (home, airport, plane) and an Ihram wearing guide. PROVIDED BY ME - Purchased high-detail 3D models (Masjid al-Haram, Jamarat, Masjid Nabawi) from TurboSquid. These are very heavy and must be optimised for Unity. - Source code, assets and .exe of the old version. - All religious content: duas, audio, text, marking positions. REQUIREMENTS - Unity, desktop only (Windows), keyboard and mouse. No VR, no crowds. - One character with 4 outfits (normal clothes and Ihram variations). The face must never be shown. - Proper collisions, smooth camera, good optimisation (LODs, baked lighting, occlusion culling). - Deliver final .exe plus the complete Unity project. DEADLINE Umrah module by 12 December 2026 (fixed). Hajj and Nabawi modules follow in February 2027. Reference video (please watch): https://www.youtube.com/watch?v=jUWzKEBLRAk A detailed proposal document with flow diagrams is ready. I will explain everything properly on a call. In your bid, please include: your Unity experience with similar 3D/architectural projects, examples of your work, your estimated cost and timeline, and the PC requirements the final app would need.
