I just heard back. He will take cash, but he can't come until around 7 pm. It's almost dark by then.
I don't know why I have such problems with lawn guys. I've been through like 6 or 7 since I bought my new house.
One kept raising his price each time he came until it got to be around $70, which I thought was too much.
One was irresponsible and let his girlfriend do the job and she mowed over some plants I wanted to save.
One just stopped coming with no explanation.
Others I contacted either did not return my messages or didn't show up when promised.
Some wanted a seasonal contract paid in advance. Yeah... pay them and it will be some excuse why he can't come.
