Original Artist - John Deere Cowboy Chords

I need some help on this. I just wrote 
the lyrics for te first verse and chorus
 i need help to finish it and add chords.
 please add all comments. This is 
the first song that i've written.
Verse 1:
He wanted to be a cowboy

So he bought some tight jeans

He wanted to be a cowboy

So he bought a Stetson hat.

Pre-chorus:

He didnt know the first thing about a cow

The only thing he'd ridden was a floor buffer

and a lawnmower



Chorus:

He wanted to be a John Deere Cowboy

A hay field hick

Now drivin that swather

Really flips his switch
