The build up of even light layer of scale/crust on the rim of the opening makes a loose seal.  

I think that the main way to scale is to have someone else doing the daily detail work.  

Not sure what your budget is, or what scale you're at size wise, but you should definitely look into Propertyware.

All other companies give you a 10 year manufacture warranty (if that much).

As you scale up, Excel just doesn't cut it. 

It is systems to scale not guru type ********.

But again this is why I'm really excited, getting our hands on these leads in bulk has been a real pain so I'm assuming there's very little investors out there doing what we're doing on this scale.

I just didn't want to sound like a greedy and pretentious bastard, so I figured saying $10k/mo was reasonable since if I can find a process to get me to $10k/mo, I believe that same process could be scaled to produce $100k/mo.

If you plan to scale and grow a business I would define your cash-flow, and allocate it to certain uses.

The thing I hate about construction (yes, even our "manufactured homes" have construction, when they are moved to a new, permanent lot), there all so many unknowns, and things that change on the spot, no matter how much research is done.
