Is $4,099 to install aluminum driveway and walkway gates a fair price?

My partner and I want to get a driveway gate and a walk way gate for our home so that we can make a backyard for our dog. The driveway is about 14 feet wide and the walk way is about 3 feet wide. We had a previous quote about a year ago for $1,100 for wood gates. This new quote seems way too expensive, but I'm waiting for other quotes.
