I need Help.
My Father is going to San Francisco, CA (actually to Marina Del Rey)
for 5 days. He needs to rent a O2 concentrator and he needs someone to
deliver it to his hotel before he arrives and to pick it up when he
leaves. He needs to wear it at night due to severe sleep apnia. He
would bring his own but they are very bulky, and his O2 tank would be
considered too volatile to take on a plane. Can anyone connect me with
a company and/or a conciere service in the area who could help me?

I need to get the help by Monday January 16th

Marina del Rey is not near San Francisco. It is near Los Angeles.
