3D Model of Heritage Buildings

I need 3 heritage buildings modeled in 3D. The models should be basic, focusing on the exterior only with simple shapes. I can provide reference images to guide the modeling process. The final deliverable should be in OBJ format.

Ideal skills and experience:
- Proficiency in 3D modeling software
- Experience with architectural modeling
- Ability to work from reference images
- Attention to detail for heritage structures
