Maximising your take solo - if you draw the pink diamond as primary target (whilst the panther statue is unavailable), pick up two stacks of coke, and raid the office safe. There'll be a small RNG variation in what you get for the coke and the office safe, but if you do it on hard and get the Elite (easy with stealth if you follow this approach) then you'll net between $1.8m and $1.9m.
