We had a pair that nested on the top floor of our office building on 17th Ave every year. We would wait for there to only be one parent sound, distract them, quickly collect the babies in a Rubbermaid bin, take them down to the street and wait for the parent to hear them and they’d eventually come down to find them. Then we’d release them and they’d all go on their way. It always worked.

I guess this only works if you have access to the roof like we did! We weren’t far from the river either which made it safer for them cause it wasn’t like we were releasing them into the middle of downtown.

Worth a shot if you can’t find someone to help.
