Commercial real estate agent - part-time possible?

[Seth Tandett]

Asking for a friend:)

He's got a solid W-2 job in commercial construction and works 45-50 hours per week. He's studying to get his real estate license and really wants to work in commercial real estate due to his extensive experience in commercial construction and his interest in the industrial, warehouse and mission critical facilities.

Are there positions within commercial real estate brokerages that he could work part-time (nights, weekends, days off from W-2) once he gets his license?
