need funds to help secure my first month of apartment til my 1st full check

I need $550 for the deposit next week.. with the rent it'll be Abt twice that but I can prob pay some if not all my 1st months rent on my first full check but it'll be my whole check and I still need the deposit. I also won't have anything in food or furniture or any house hold items as I'm starting over from scratch w almost no belongings but clothes and a few sentimental s
