Car moving help (short gig, involves driving)

I’m moving out of the Bay Area and shipping my car across the country. I would like the car to arrive around the end of August, but I’m leaving the Bay next week. As a result, I’m looking for some help with coordinating car pickup after I've left the Bay.

Specifically, I’m looking for a trustworthy, safe driver in or around San Francisco to do the following:

1. Work with me to find a 3-day window between August 20-31, during which the car shipper will pick up my car, and you are available to drop off the car to where it needs to be picked up.
2. Arrange for me to handoff the car keys and a garage door opener to you, likely via a lockbox in SF.
3. During that 3 day window, be available to drive my car from the garage in SF it’s parked in, to the car shipping truck’s meeting point (shouldn’t be a long drive). The shipper will call you and you will take the car to the pickup location they specify.
4. Take the garage door opener to a USPS office and mail it. I will leave an addressed cushioned envelope in my car for you to use. It can NOT be dropped off in a mailbox due to its size. I’ll reimburse you for the postage for the garage door opener.

Pay is $150.
