back to the OP, if you have a CDL-A, why are you trying to downgrade yourself to become a package car driver?!?!
look for jobs that will utilize that license! don't start at the bottom of the barrel, hoping to hop into a package car.
heck, try FedEx HD or Ground first to see if you like driving to 100s of stops per day during peak season (check your local craigslist job boards ~transportation section "fedex" in the search bar) depending on your area some FedEx feeder contractors as well as package car contractors are both up in my area... currently, my hub is looking for half a dozen right now
or try applying to the peak season driver position at UPS in ~2 months... if you shine, and become one of those "off-the-street" drivers after new years, then you skip all of that waiting in the warehouse (YMMV since some hubs need drivers more badly than others )
