"you might be able to rent something like this in your area for $571/day"
I see where you got that figure, weekly rental of $4000 divided by 7; in my area, it doesn't work that way. (Probably because everything ELSE seems to be more expensive here)
There are a couple places that rent that type equipment and smaller, both use the same formula -
1 - a "day" = 8 hours on the hour meter
2 - a "week" = 7 days, which means 7 X 8 hours (56 hours) on the meter
3 - If the daily rental is $300, the weekly is 3 times that (but still only 56 hours; anything over that gets charged by hour, or day if it's a full 8 hours)
4 - Units get delivered if very large, or a few other options if they're smaller.
5 - Unit is delivered full of fuel; you can return it that way, or pay about a buck more per gallon to re-fill it if you send it back NOT full
If the company in the link uses that same formula, $4000 (a week) would be $1333 per day (if it were in my area; hopefully other areas are different)
Interested to hear other than the above, I KNOW I'm getting screwed on steel prices compared to other parts of the country... Steve
