I just built my cages out of 1x1s (ripped 2x4s) designed around the big oil drip pans for garages.  They have dipped vinyl 1/2" hardware cloth on the bottom and regular 1/2" hardware cloth on the sides.  They stack on top of each other and you just clean the trays (easier if you line them with newspaper).  Very easy to build.
I've kept them indoors, but like in a storage shed area.  I had a tarp on the floor (they can fling food and poo far.)  I have only kept Coturnix.  They do great outdoors, so if you could do that setup right outside your walk-in basement, that might work well, if you're considering Coturnix.
I think the type you want just depends on what you are looking for.  Like Nabiki said, Button Quail might be the best if you are wanting to keep them indoors.  Coturnix would be the best for meat and eggs.  I'm not sure if there are Celadon Button Quail.
