Default kiln questions

I'm planning to get a kiln custom made, as I'm based in India, and the ready kilns will be too expensive considering import duties and shipping. I have a few doubts,

1)Since I'm more into sculpting, I hope to have an internal chamber about 1'x1'x1', front opening. What is the max size of glass I can anneal in it?
2)Most often I'll use the kiln to anneal small pieces 1-2" in length. Will that lead to energy wastage since the chamber is large? Also do you'll keep the kiln at annealing temp the whole time you work to keep popping thing in as u make them? My work develops little crack while cooling.
3)Where is the best place to have the heating elements located so that the heating is uniform? Is it common for a kiln to be ventilated for even heating?
Does it matter if the insulation material is ceramic fibre and not fire bricks if the ceramic fibre is completely covered with steel from all sides? Since ceramic fibre is cheaper than brick.
4)How long does it usually take a kiln to reach annealing temp from room temp?

Maybe thats more than aa few doubts...
