home lifting

[jerry]

I HAVE A HIGHLAND HOME WHICH IS 10 YEARS OLD. I WOULD LIKE TO RAISE IT UP AND PUT A BASEMENT UNDER IT. WHEN IT WAS PLACED I POURED AND FINISHED ( THIS IS MY PROFESSION) A CONCRETE FLOOR.IT IS ON A 4 FOOT, 8 INCH POURED WALL. I WOULD LIKE TO ADD AN ADDITIONAL 4 FEET. CAN IT BE DONE AND YOUR GUESS HOW MUCH IT WILL COST TO HAVE IT DONE BY AN EXPERT?
THANX A LOT,
jerry
