Help Cassandra’s family

I am a young single mother of a beautiful little girl and we've had to move from three different states since she's been born. I am now in a state where I feel comfortable raising my daughter I have a decent enough job, but I'm running into a tough situation. We've been staying in a hotel for over a month and I finally found an apartment that I can afford with my salary. The problem is paying the weekly rate at the hotel is making it impossible to save enough money for first months rent and deposit. I've been approved for the apartment and can move in as soon as Thursday which is how long I'll have the room for but I'll be about $300 short in order to cover all cost for the move. I need help asap so that I don't loose the apartment and would greatly appreciate any help I can get. All I want is to provide my daughter with a home before christmas. Hopefully I did a good job explaining my situation but if there's any questions or anything I can clarify I'm more than happy to do so.
