You would like to put the drain at the level of the footing or at least well below the level of the dirt inside. Perferated pipe around the outside and run down hill to city storm or daylite or sump pump it out. So it would be a little digging a little hauling gravel to cover the pipe, filter cloth to cover that and backfill. If you do go to all that you may as well waterproof the wall with a tar like product up to landscape level.
Sounds easy if you say it fast.
