Historically Accurate Blender Reconstruction of a Concrete Bunker from Photo References

I am looking for a Blender 3D modeler to help reconstruct four historical concrete bunkers as part of a larger historical site model. This is not a concept art project. The goal is to create rough but plausible and dimensionally controlled bunker models based on the reference material I provide. I already have: an existing Blender project GIS / QGIS footprint data and dimensions historical reference photos notes and working files for the site What I need: rough 3D models for 4 bunkers correct overall dimensions and footprint plausible roof and wall shapes based on references main openings / gate areas modeled in a simple way clean and organized Blender geometry models that fit into the existing site reconstruction At this stage I do not need: final textures ultra-detailed interiors highly detailed props artistic redesigns The priority is: correct size correct massing correct silhouette consistency with the historical references Deliverable: updated .blend file or separate Blender files for the 4 bunkers Please apply if you have experience with: Blender architectural or hard-surface modeling working from photo references and measured footprints In your proposal, please include: relevant portfolio examples your estimated fixed price for 4 rough bunker models estimated turnaround time
