You can probably get the lot for £70.
That's based on it being an external bottom bracket. You might also need to borrow a bb removal tool if you don't already have one.
I used one of these on a singlespeed mountain bike I built:

It took plenty of punishment on one of my weekenders. Check with the seller because they do it in quite a large range of teeth. I think I used 44/17 on the mountain bike.
Thanks for the help, will look into it!
