I have also considered this. Honestly I'm not really sure what the difference is between the UPS mailbox (used a street address) and some of the smaller companies nearby that rent mailboxes (with their street address).

It seems like the same thing, but just different costs.

My other concern is I don't know if my work will have any issue with that address showing a mailing facility on Google maps as opposed to a residence/apartment. I highly doubt they would look though and I'm not really sure if that plays a factor at all.
