Roblox-Style UEFN tycoon Map

Job ID: 40469280

Budget: $30 – $250 USD

Looking for an experienced UEFN (Unreal Editor for Fortnite) developer to build a high-retention, fully functional Incremental Base Tycoon map from scratch. The game loop is heavily inspired by successful Roblox tycoon mechanics but completely transformed into a unique, legally safe sci-fi aesthetic. 
The entire map must be constructed using 100% native Fortnite devices and prefabs. No external custom modeling or custom audio imports are required. A complete, highly detailed Game Design Document (GDD) with exact device wiring requirements will be provided upon contract startup. 
Core Gameplay Mechanics Required:
1 Automated Resource Generation Track: Item Spawners dropping gold items onto a moving conveyor lane, which feed into a Capture Area Device to update the player’s score profile. 
2 Holographic Upgrade Network: Upgradable zones locked behind Conditional Buttons. When spent, Prop Manipulators/Mutator Zones reveal structural expansions (walls, doors, better generators). 
3 "Overdrive" Interaction Terminal: A central physical lever that players can activate every 60 seconds to trigger a Sequencer, boosting coin spawn rates by 3x for a 15-second duration. 
4 Clean UI & Performance Optimization: Customizing native HUD Message Devices and scoreboards to cleanly track and display energy/credit counts. 
Strict Project Constraints:
Budget: Fixed budget of 30,000 PKR (or equivalent USD). 
Timeline: Complete delivery, including QA testing and Epic Games Creator Portal publication review, within 10–14 days. 
Asset Rule: 100% Native Fortnite Assets only. No external intellectual property, trademarked names, or copyrighted elements from Roblox or other franchises. 
Milestone & Payout Schedule (Non-Negotiable):
Payments will be strictly bound to functional milestones: 
Milestone 1 (30% / 9,000 PKR): Core logic integration. Item spawners, currency tracking, and upgrade buttons working seamlessly. 
Milestone 2 (40% / 12,000 PKR): Visual map architecture completed using native sci-fi/military building prefabs. 
Milestone 3 (30% / 9,000 PKR): Final multiplayer stress testing, submission to the Creator Portal, and successful transfer of the functioning Island Code. 
Applicant Requirements:
Must have a portfolio or proof of previously published Fortnite Creative / UEFN maps.
Must have a clear understanding of linking Verse code or native device channels efficiently to keep memory consumption low.
Excellent communication and willingness to provide a basic prototype block-out by Day 4.
