Chose the first one, age 30, saying he's not married.

Can't choose someone too handsome, strong, and vigorous—after all, we eat and live together, the old man will definitely get jealous.
Also, too handsome guys might distract me and affect my trading.
How much do you think I should pay him per month?
I cover food and accommodation here, just have him watch the market fluctuations during my rest time, call me, and since he wants to do trading, I can teach him.
I'll have him come over tomorrow to report.
As for the salary, I told him it will definitely be higher than what we pay locally!
