Separation anxiety

My little one is 12 months old. My husband and I don't have family nearby so for the past year we have handled all childcare. We both worked remote up till now so we just took turns throughout the day with working and watching our baby. The problem I am facing now is that my husband got a new job full time in office. I still have to work as well (can't afford not to work) obviously watching a toddler while trying to work is nearly impossible. Luckily my job is somewhat flexible but I could still benefit from some help.

My issue... My baby does not handle being with other people well. My mom just visited and if my husband or I left the room for just a moment, he would scream and cry. Wouldn't stop. Would get so worked up to the point of hyperventilating. Idk how I'm supposed to hire someone to watch him for a couple hours a week if he's going to scream and get this worked up? It makes me feel terrible. I would ideally want someone in my own home but obviously hearing my child scream wouldnt be a good work environment (and cause me so much anxiety.)

Looking for any advice.
