Where could a 20 year old find a decent job in nj?

I'm a 20 year old single father, currently working at a car dealership and only make enough money to pay the bills, sometimes not even that. Thank god I have some money in the bank. I make $130 on a bad week.... and most weeks have been bad. I'm willing to do just about anything except janitor work, sales and mcdonalds... please help me. I'm struggling right now
