New Tank Upgrade question

Well its time for an upgrade and I am having the LFS build a glass tank. Before I go there and ask them if this is possible I thought I would post on here and see if anyone has any opinions. Here is my situation. I need a larger tank with good width but I also have to make sure I can move it because I am renting and the next move will be a house purchase so I have to make sure this tank will fit through the door. To go into the basement is pretty easy in my current dwelling . Just straight through the back door and down . The Door is 32 wide. The fish I currently have need more width than the height and they are glass bangers. Would it be possible for them to build a tank 28" wide 24" high 84 " long? Would 1/2 " thick glass do the trick ? Or is this over doing it ? Thank you for any input

I would honestly go acrylic it is way lighter but I don't have access to acrylic around here and don't know where I could get ahold of one that would be decently priced and to get it shipped here. Any idea's on where I can look ?

Thank you Gill I will look into having the bottom tempered . I will have quite a bit of substrate in there. And Ragin ill definitely look at that website . Im pretty sure these people who are building it will have braces placed onto the tank. I wouldn't take it home without ! Im pretty picky and I am still iffy about letting the lfs build a tank but they have told me they have built bigger and their main display tank is close to what I was looking for . Another year or two of space is all I need before I can go bigger . Thank you .
