Overnight Sitter Needed For 2 Nights For 1 Child In NE Portland

I am a single mom who is looking for occasional support, including overnight stays, as I travel for work. I have a work trip the first week of February and am looking for someone to stay overnight and help my son get to and from school, including overnight. My son is in kindergarten and has before and after care (can be in school 6:30a-6p), so hours would be as follows: -Mon 2/3, pick up from school by 6p and then help with dinner and bed at 8p. Stay overnight. -Tues 2/4, wake up (approx 6:30a), breakfast and get him to school, before care is open starting at 6:30a, but I usually take him between 7-7:30. Then pick him up by 6p, help with dinner and bed at 8p. Stay overnight. -Wed 2/5, get him to school in the AM, then that is it! I need a reliable, trustworthy, friendly sitter that I can hopefully use in the future.
