Waterproof shed base (estimate only)

Water is leaking into my shed between the concrete slab and the large bricks, down one side only. I need someone to dig slightly down (max 10cm I guess, and it's exposed in some place) and water proof this junction. I would like a rough estimate (preferably without viewing the site) please. I don't want people to go to the trouble of a full quote until I know the ballpark cost.
