How much above the cost of the modular home will it cost to make a modular home living-ready? - what is modular combat system (mcs)

I think the purchase of a modular home to put on a property in MI, the cost of the house itself is $ 73K. Has anyone a rough idea of what it would cost to build the house and all the work into it as the foundation of electric, utilities, interior walls, plumbing, heating, cabinets, etc.?
