I guess it would depend on how well off I was. If I was dirty rich I'd probably have some crazy custom built 5000+ gallon reef tank. At that size I couldn't do all of the maintenance by myself so I would have to resort to hiring help.
If the size was more manageable, then I'd be inclined to think that I'd do my own maintenance, even if I could afford to hire help. I'd probably spend big bucks up front on a proper setup that will make maintenance as trouble-free/automated as possible.
I think most people that frequent boards like Canreef are more than casual aquarists, who enjoy the hobby through hands-on experience (sometimes painful).
But hey, we can try a little experiment. Pass me a few million and we can see if I'd change my behaviour.
