That's at 40 hours per week, though. I suspect most people interested in this service could get a lot of headaches dealt with at ~10 hours, which raises the possibility of a PA taking on four clients and making median salary.

That's not going to get your grocery shopping done, but 10 hours/week seems like it would comfortably cover many people's paperwork/bureaucracy hassles.

This would be an awesome service. You have your emails auto-forwarded to them, you pay them for 10-14 hrs a week and send them any information you want them to process. Then they prepare daily emails or phone calls for you.

These people could have like 3 or 4 clients a piece.

no one is saying full time. But I could see the value of being able to hit up someone when necessary, right?

In fact, that person probably wouldn't do everything but would help "administer" it, eg. hire a CPA to do taxes (and audit them quarterly), occasionally book a flight or find a hotel, come in once a week to spend a few hours to sort through mail, etc.

I hear a lot about "virtual assistants" but I imagine this person could fit in 4-5 clients per month which could mean $5K/month and that translates to a pretty good salary.
