Also we are working with very limited manpower. 

We're running about 800,000 CMAs every day, I can't even imagine putting real person manpower behind that :).

Something changes in their schedule, such as a big job gets awarded to them so they blow off any outstanding estimates they were processing, they lose a key employee so they don't have the man power to pursue the new projects they have looked at so they blow them off.

It's quite a process and will demand quite a bit of manpower to facilitate, but we're trying to set up as sophisticated a process as we can.Also, do any out-of-town investors that purchase at various auctions have some general advice that may pertain to any auction in general?

Local governments devote significant manpower to cleaning up the signs, which violate sign ordinances.

Some PM took over too many areas than they can handle.A SFH PM may have difficulty & manpower to handle a 100 unit complex.

If you haven't looked into the C-site dam, that will the largest job in Western canada if not canada going - oil's at a standstill which put s down the big four sites up north at maybe 60 percent man power if not less. c-site is a ten year ish job to. 

my car got hit my basement flooded  it was not good.. called insurance .. issue will be man power to fix all this stuff.. 

Yes, any PM is going to have their mark-up, but they need their cut because they are dedicating their manpower/hours to bidding, communication with you, supervision, etc.

You have the man power and the experience of owing a small business already.
