USA, California, Fremont – looking for a family

Hi. We’re an Italian family based in Ravenna. One of our kids – 15-year-old home-educated boy named David – has been admitted to the Summer Bootcamp at 42 Silicon Valley, Fremont (June, 19th to 30th). So we’re looking for a family willing to host him from mid-June to the beginning/mid-July. We can offer hospitality in the same or other periods (for one person). Otherwise, David can teach Italian, maths, coding and also look after children (he’s an amazing babysitter with lots of experience with his little brother) or help in the house (obviously when he’s not at the camp). Thanks for any answers or tips!
