When starting a Janitorial company you will need your Brute, caddie bag, 4-6 spray bottles, a few cleaning chemical supplies, mop and bucket, and a upright or back page vacuum.  Total investment at this point is only $400 but your potential earnings that can be produced from this small investment is endless.  When David started with a list very similar to this he was producing over $3,000 per month in volume just after 90 days.  Most of this volume was being produced by a small school he landed in his first 30 days.
