Ideas on what this profession could be? 20.2.6 > 29

So, I've been trying to determine if I already know the man that I will start a new relationship with (whenever that maybe - not rushing, just inquiring).
I asked Yi "What does this man do for a living?" and I got 20.2.6 - 'Overview' // changing to 29 - 'Dangerous Depths'.

So my thoughts are Hexagram 20 is referring to, maybe, a sales person, "traveling out in the community to see customers" . Hexagram 29 - has reference to Water, the River, and even read a "a cold drink".

What other kinds of professions do you see in this casting?

Thanks in advance!!
