Creation of 3D models of landmarks

We need a large number of landmarks as low-polygon 3D models with texture. The 3D models should be kept very simple, because the number of polygons should not be so large. If possible the 3D models should not use more than 500-3000 polygons. As 3D format obj, lwo, fbx may be used.
