That reef tank is breath taking
, would love to have a big enough space/wall to do something like that, maybe in my next office if thing go well next year.
As to what I would do with 5mil.
Buy 5 more houses not massive or expensive just in right areas.
I would then build my business a lot quicker with the funds to do it and make Dean head of national contracts
I may take a holiday for a couple of weeks also
