Well it will depend on what is needed for the repair.
And if you are doing both front and rear.
If just doing front pads and nothing else is needed then you are looking at about $200 +/-.
If need rotors and or caliper then your looking at up to $1k.
Then if you are also having the rear done. And need drums and/or wheel cylinders your looking at around $1,500 - $2,000.
And I believe the parts are going to be the majority of the cost. And I am pricing high cuase I don't know the labor or cost of parts in your area.
If you think you can handle the job you can save quite a bit. The front brakes aren't to difficult to do. The pads would cost around $60.
The rear brakes are a little more difficult to do and need special tools. The tools shouldn't cost any more than about $40 and the shoes around $40.
If you feel you can do the job let me know and I can get diagrams and removal instructions for you.
