If you're set on the boring method you could do worse than find an LA 
version of these people:

Mini piling rigs are very versatile and can be fitted into restricted 
areas. The piling case could be used as a duct for a pipe or even a 
drain itself, subject to approval by someone who actually has firsthand 
knowledge. They can also be aimed with reasonable certainty of arrival.

What Tony said about friction and possible obstacles says it all about 
manual operations.

Good luck.
