How To Compost an Entire Acre Of Land

[andreaharps]

I'm brand new to this 1.5 acres.
The grass is pretty where there's irrigation. It's not native grass.
The rest of the grass I can't determine what it is.
From what I've read, the best way to get a healthy lawn is to mulch the grass when you mow. To re-seed on top of the healthy grass to make it full, thick and it will keep out weeds. And to compost the entire lawn.
I get that.
I haven't started my compost bin yet, so I'm far away from having enough compost to do the entire acre, or 3/4 of an acre.

How do I find compost that's inexpensive enough to do an entire acre?
Do I spread it by hand and then till it in?
Can I just dust it on top and let the rain handle the rest?
When is the best time to do this for a lawn?

Lots of questions and confusion...
Should I just start with a smaller piece of the land and see how it goes?

Side note: and I can post this elsewhere if it doesn't fit this topic...but...
If I have multiple types of grass (bermuda where there's irrigation) and who knows, elsewhere...
do I just plant bermuda seeds everywhere or go with a native grass in the "who knows" section

Sorry for being so scattered with my questions...I'm just confused and overwhelmed as to where to start...
Thanks!!
