Dog with cracked nail - Vet costs?

Anyone had any experiance with this?

My dog was limping on his back paw and after checking it seems he has cracked his nail quite far back. I know dogs have a 'nerve root' in their claws and after googling it seems it is something the vet will have to fix (as it's so close to the base) but I'm wondering if anyone has any idea the general cost?

It's just that a bee sting a few weeks ago ended up costing me hundreds with drips and tests.
