£1,734 is a lot of money. A brake job is one of the easiest things you can do on most cars, including your Fiat. New rotors and pads are available to suit your driving style, mild, performance, or race with prices to match. Do some research and pick a set of rotors and pads to suit your style.
You need a jack and some ordinary hand tools for this job. Nothing fancy. You certainly don't need a lift, an impact wrench, or even a torque wrench. There are plenty of of videos available to show you how to do it.
If you're completely helpless when it comes to turning a wrench, hire the 16 year old kid in your neighborhood to help you do the job. Toss him 100 pounds and you'll both be happy.
The job is not rocket science.
