just put a mulch plate and sharp blades on your mower, then mulch the leaves into the ground.
Your clients don't really care HOW you get their yard clean, as long as it looks clean. Besides, in leaf season, it'll be covered in leaves a day after you cleanup anyway...
Forget the logistical headache of bagging, hauling, dumping leaves. That's for suckas!
