I suggest ady make a eurotrip and visit guys that made models and props instead of make it alone. So with that way he can have more materials to use with less cost.
I know that its good to make models for bases and stuff but a more easier way is some 3d mapping (not pure 3d! Its painting/photos combined with 3d that give a real look.) Same effectiveness less time and cost.
Im just throwing random ideas :)
