They are the people you see working on the large erections of steel at a refinery. 

Yes there are, @Ron Steele , but they typically only place capital for large deals. $10 million would be a small deal, $20 million would be interesting to a lot of these guys.  

It interesting when you compare Pueblo to other steel towns gone bust.

That goes for other construction such as SIP (Sturctural Insulated Panels) or steel framing. 

Or open a steel manufacturing plant if you had enough money?

I might note that in addition to suggesting a possible slot of open house times, there are some software options out there which allow you to schedule showings immediately after you've listed the unit, and it allows you the ability to also auto-request applications (keeps everything easy and in one place - so listing, tenant screening applications, leases and other tools like rent collection and maintenance tracking just to keep the process seamless); would be happy to share more info. 

Cold calling sucks but after the 100th one you'll have nerves of steel and with the right scripts you'll start filling up the pipeline. 

There is some industry around ( I work at a steel mill about 30 minutes from home) there are also so oilfield operations around.

I tell my agent to write the offer, and he says "OK, but before we make an offer, you need to understand that the entire house has galvanized steel plumbing, which will fail.
