Buy a plot next door and build a banquet facility/hotel.. it will be booked forever.
(EDIT: after reading teh stories linked by
@MrsScrew below... wow.. looks like
@koleszar is correct in the use of "slave labor".. I will leave my original response below for original context)
Was once in an Asian city and I always looked for natural wonders to visit on business trips and,in lieu of that, man-made wonders. This would fit. But there I went to a Hindu temple built from caves and noticed it was dirty (human dirt, not guano). On my way to the airport my cabbie suggested a stop at Buddhist temple.. it was spotless. I had to take my shoes off.. but worth it.
What does that have to do with the OP story? I dunno.. I guess I am wondering about the long-term upkeep of this new site. I'd imagine the Taj Mahal and other Hindu sites are very well kept.. but haven't been. I guess we shall see.
@koleszar Volunteers are "basically slave labor"? I do wonder about the building permits and such as it relates to volunteer labor. But what should be a point of pride.. volunteers building it.. taking pride and ownership.. "slave labor" is very insulting imho.
