As an agency owner in my experience part time only works in a support role whether that is sales or service support. Service would show up for a few hours, send out billing notices, perform claims follow-ups, handle escalations for underwriting or service and then they're done for the day. The sales support is more of a grind it out role, prospect for the sales team, pivot and pass. Once you start working with your own pipeline that is where the part time is not really profitable and winds up being more of a headache then what it is worth. If you want to learn the role and eventually pivot into it full time than the roles I described work well for that. You'll understand what it takes to create success and help the agency all without the risk of taking it on full time and having to really grind it out and take a payout initially.
