The saw cutting is the easiest part. Farm out the bucket carrying - that is going to suck.

Figure about a 5 gallon bucket of debris for every foot or so. You will be carrying out concrete, gravel and dirt.

I just did a similar project. During a basement finish out, I relocated a sump pump pit, trenched 50' for plumbing lines, and moved the central floor drained about 5'. That was a ton of work (by myself) and your project is bigger.

I would rent Home Depots walk behind concrete saw - it has a hose connection to keep down the dust. A 4 hr rental won't cost much. Demo hammers work fine (also at HD) as do the larger jack hammers. Worst part about the big tools is carrying them down the steps.
