Landscape Heightmap / Michigan's Southern Lower Peninsula Shape

Need a freelancer to create a landscape resembling the shape of the Southern Lower Peninsula of Michigan (the flatter southern portion Grand Rapids/Lansing/Ann Arbor/Detroit area, bordered by Lake Michigan and Lake Erie) using World Creator or a similar terrain tool. This is for a survival game, so the terrain needs to support real gameplay, not just look good from a distance. The final deliverable should include either a heightmap or a UE5 project file. Scale: roughly 100 km² (about 10km x 10km) not real-world scale, just the region's overall shape/coastline compressed down to that size. Terrain feel: realistic, grounded terrain suitable for survival gameplay natural rolling hills, rivers cutting through, gentle elevation changes, and believable ridgelines. Should feel like a real place you could walk, forage, build, and navigate not mountainous or exaggerated, but also not flat/featureless. Needs enough natural variation for things like: Walkable/buildable areas that don't feel artificially flat Some higher ground for vantage points/lookouts, without being unclimbable Terrain variety that would support different biome/resource zones later (forest, open field, coastal, etc.) Water features: would like some smaller inland lakes/ponds and rivers scattered through the landscape, similar to how the actual Michigan region has tons of small lakes and waterways in addition to the big coastline not just one giant edge of water, but natural water access points spread across the map for gameplay purposes (fishing, drinking water, natural barriers/landmarks). Should NOT be raw compressed real-world elevation data (which looks too jagged/spiky once squeezed down to this scale) needs to be hand-tuned/artist-adjusted for actual gameplay feel and traversability. The coastline and any lake shapes should be recognizable, but exact real-world elevation accuracy is not required. Deliverable: 16-bit grayscale PNG heightmap, 8129x8129 resolution (UE5's recommended Landscape size), OR a UE5 project file with the Landscape already set up. Please share relevant examples of similar work (survival game terrain, real-world-inspired landscapes, or general Landscape work) and your experience with terrain creation for this type of project.
