mulching and lawn question

Hi all, I hope everybody is staying well. I have two questions....we were contacted by the man who cuts our grass and he said that he received notice for landscape professionals that they must modify hours and he needed to wait for specific guidelines to do any work....has anyone heard of this? I have seen so many lawn companies out doing work....sort of baffling so just thought I would ask. Next question...any ideas where to have mulch delivered from that one can call and get through? Are these places even open? Also I am looking for someone who has the ability to get mulch and deliver it and if that is you could I get an estimate?? Thanks and will wait to hear.... Susie
