Where/how can I find/buy/make building footprints for Kent County, MI (Grand Rapids, Wisconsin, etc)?

Question

I'm in big trouble and need help. I'm really hoping someone in the Stack Exchange community is feeling particularly helpful and will go the extra mile for me. I'll owe you one in whatever medium you wish.

Anyway, we have 11 days to deliver our product to our customer in Michigan but we don't even know where to find the data we need. We just paid the county $5,000 for data that is complete garbage.

We need building footprints for Kent County, MI along with their associated street addresses.

Primarily we're looking for Grand Rapids and some of Wisconsin, MI, but if someone had access to this data, we'd like Kent County entirely just to be safe.

Do you know anybody/any company that would be able to provide this, or help us find someone that can?

Honestly, I think my companies future depends on the successful execution of this contract and we're out of ideas. The Kent county GIS and their associated data provider aren't cutting it.

Any ideas?

Thank you in advance.

Since you are short on time, I'll start the ball rolling, though I have no idea if this will work in your case (or if you have already investigated OpenStreetMap):
