I am in a lower COL area, but I have done similar work (driving a child to and from parental visits). For each one way trip (about 30 minutes total), I was paid $15 and for both pick-up and drop-off (two periods of 30 minutes), $25. For me, the extra money was definitely worth it, so I bet you can find someone with the extra time who wants to pick up a little extra, just offer pay that is reasonable for the time and effort.
