Get help with paying bills or free stuff.

I am currently living in a shelter with my 3 kids and have been apartment searching for months and I finally found an apartment that will except me with my rental history but I have to pay 1st and last month rent. Unfortunately I do not have the amount that they are asking for and I really need this.
I'm tired of living in a shelter. I was wondering if there was any way I can receive any type of assistance.
