How much should it cost to have aluminum siding installed?

Question:I'm a masochist, I mean rehabber, who's interested in getting a house to rent out and make some money. In running the numbers, I've come across something in which I have no experience: installing aluminum siding.

I want to know how much it should cost per square foot of the house, and/or how much it should cost for a wall of an example size. I need to have a mathematical basis for running the numbers before I jump into a project that could either bankrupt me or require a year of slow saving and work in order to complete.

There's no such thing as a dumb answer... although plenty of people give it the ol' special ed try. Please explain how you get to your answer, because that's what most important.

Thanks in advance.

Answers:
Siding, in this case using ten feet square as a basis, is about $35.00 a square. Go to Home Depot and have them run up the numbers for you like I did. They'll give you the entire make-up with all the facts and, three different price ranges. Another thing, if you get them in a good mood, you may get free delivery, that's a savings in more then one way in itself.
Then you can go to Lowes or some other place and compare notes.
