Andrea: Cost depends upon the amount of work needed, sometimes the jack pads or piers need adjustment, other times leveling is simple adding or adjustment of shims. Best is to get a manufactured home expert out to view your unique needs. Porch does not have manufactured home specialists to refer, so I did a quick Internet search "Las Vegas manufactured home leveling" and found this company in your area had the best reviews. We do suggest you obtain multiple estimates from several local companies. https://www.richardsmhs.com/
