javascript Regex to extract all sentences that contain a certain word 2 times

For example, I have sentence (str1) which have 2 word contractor and (str2) which have 1 contractor word. I need a regexp that will extract all sentences that contain 2 word contractor 

var str1 = "Before hiring your chosen contractor, be certain to get a solid estimate in writing because not all contractors are honest and upfront in their quoting of costs."

var str2 = "Before hiring your chosen contractor, be certain to get a solid estimate in writing."

I defined a sentence as anything preceding a ., ? or ! here. Feel free to adapt to your needs.

To catch one contractor:

[^.!?]*\bcontractor\b[^.!?]*[.!?]

Every match is a sentence with one or more "contractor" in it.

To catch two or more, use this:

[^.!?]*\bcontractor\b[^.!?]+\bcontractor\b.*?[.!?]

It reads aproximately as: match everything other than sentence ending, followed by the word "contractor", followed by more non-sentence-ending characters, followed by the word "contractor" again, followed by any chars and one sentence-ending-character.

Make sure to set the global g flag, so that multiple matches per line can be found. You'll also have to trim the outcome since a sentence can begin with a white space in the pattern above.
