That's not too bad actually, was expecting worse.£15 a brake is about the average price.
I'd rather get a Pro to do it to be honest, my past record in bike maintenance is less than impressive.They might just need the old zip tie your brake lever to the bar and leave over night trick. If that doesn't work you could bleed the brakes yourself. Hope's are easy to work on. All you need is some 8mm hose for the bleed nipple, a bucket to collect the old oil and a sryringe to fill the brake with oil. It only takes 10minutes.
How about the 4yr old pads?

I thought if I went 'just a bit further' I'd get to some awesome singletrack.... never happened
