Here are a few carpeting and flooring installers. I have used the first guy several times. When you get your estimate, ask about disposal, new carpet padding, and tack strips if needed.
Jeff Mason -- Lowest Cost Flooring
I have used him several times, he has the best rates. $2/ft in 2021.
I haven't used him for carpeting, but he is also $2/ft as of 2021.
50c per foot, you buy
$1/ft to install, you buy, he recommends Cheneys in Plymouth
Grant -- AllCarpetMN.com
$3.50/ft, includes pad and install, but not removal
He could come next week in 2021
75 cents per foot, $1.25 if tack strips needed
Includes carpet pad, disposal is extra
Scheduling 3-4 weeks out in 2021
