Property Preservation Process

[Joe Jackson]

I'm trying to find information on what a property preservation company's process is. When a preservation or field services company is asked to inspect, clean, maintain & preserve a REO property, who is responsible to come up with the bid and what does that process look like? If the preservation company subcontracts the work out, do their vendors give a bid or does the preservation company set the price for each service and tells the vendor the price?
