How to do an intense home retreat?

I am planning to do an intense home retreat, of 2-3 months -- just like a ven. Mahasi Sayadaw retreat: which means 1 hour walking, 1 hour sitting, all day long, short sleep, repeat. The thing is, to do a long intense retreat in this tradition (ven. Ajhan Tong Sirimangalo technique, to be specific), I think you need a teacher. Is there a way I can do a retreat alone at home, with some other technique maybe? I would like as much advice from as much people here -- in case they know of ways to do a home-alone *intense* retreat -- without a teacher.
