if you or one of your friends, can operate an Excavator. rent a small one with enough reach to do the job, and dig a trench alone the side of the house where the leak is. and about a foot deeper than the foundation and continue the trench to a underground drain, or roadside ditch. then clean the wall with a waterhose and a brush. cover the bottom of the trench with about 6" depth of # 57 gravel. lay a double row of 6" plastic pipe with the little holes in it. { Perforated pipe }the full length of the trench. coat the wall with a good concrete sealer and let dry, then coat the wall with a good thick coat of tar. then cover the pipe with a foot or more of the gravel. then use the dirt and refill the trench. this should take care of the water problem. and for about a 3rd or less of the money your talking about. this is the way I did mine when I built it, back in 1986 and never had a problem with it. hope this helps and keeps you from being robbed.
