Welcome to our forum.
Look beautiful...butFigure any repair is going to cost AT LEAST 3 to 4 times more (personally, when I was doing service work, I'd turn down these type of jobs).At some point it will flood, costing you thousands to repair. Yes, you may have a sump pump, but sitting idle for years, by the time it's actually needed, it wont work.It's far more difficult getting into and out of a ground level spa.
