Help! Abandoned baby squirrel

Found a wet baby squirrel on the ground in SE Portland under a car at 8:45 am... went to do some errands. Came back at 11:30 am and he's about 6 inches up a telephone pole making little chirping/crying noises. He's cold and mostly unresponsive to cars, dogs, joggers, etc going by. I called a squirrel rehab in Vancouver and they are closed. Can anybody rehab this baby? I unfortunately cannot. If you have the ability to rehab this baby, DM me and I can give you the intersection where he is located. 1pm UPDATE - I went back to the location and the baby squirrel was back under the car in the wet mud. I sat on the curb for about 40 minutes while cars, kids, bicyclists with boom boxes, a bunch of a-holes on loud dirtbikes, dog walkers, hungry crows, and every other loud and threatening thing passed by scaring the little guy. Finally, he got more comfortable with me than the ruckus around us and let me capture him with a blanket. He is currently safe in a ventilated cardboard box. I'm thinking of taking him the the Bird Alliance of Oregon, I just called and left them a VM to ask if they euthanize, I'm waiting to hear back. - they called me back and confirmed that they'd kill him since he's not a native squirrel. I can't live with that. 4:45pm Final UPDATE - Portland squirrel lovers came through! Someone who saw this post DM'd me their sister's phone number, I got in touch with the sister who has rescued a baby squirrel in the past. Sister knew a really experienced squirrel lady and passed my number to her. The squirrel lady and I made contact and Francis (I named the squirrel while he was with me) and I made a trip to Beaverton to meet up. Squirrel lady has been rehabbing baby squirrels for years and has a complete setup, including developmentally appropriate indoor cages that
