You can actually do it at home cheaper than that (but I say this as someone who wouldn't have been doing the "heavy lifting", terrified that my son would not be delivered properly, but not having to push him out of my distended body), but if you have problems, it becomes a medical crisis requiring an ambulance and possibly even NICU. There can also be ancillary issues, such as tearing of certain tissues, that require sutures and other medical care.
Hard to recommend, but some people do it.
