I dislike the door count as a metric also.

I would like to get the names of non-profits in MD that run sober-living homes.

$1000 per door is a grand slam out the parking lot home run!

That should be no more than a five hour job including running to hardware store.

What you need to learn in your 20s is how professional business works, how to manage people and projects, how to run an organization and how to sell ideas and concepts.

Doors are irrelevant.

Still have 10 doors up there, and always pursuing deals.

If the drywall cracks in the next year or two, or the doors start to stick, then you likely have a larger settlement issue going on, and will likely need to call a foundation repair contractor. 

If it discharges 5 foot from the building and there is a low spot running back to the building, then it is going down hill back to the building.

Every little thing in the project should be in writing, even down to the door stops :-) See my tile spec sheet below ...Two problems with your post though - 1) In my experience, most problems come from the customer changing their minds constantly.
