Will it be cheaper to drive my car and attach a trailer or hire a moving company to move my studio apartment?

I'm moving at the end of the summer to Atlanta GA from Chicago IL. I drive a 92 Chevy Cavalier. Should i rent a small trailer and drive down there or hire a moving truck. I don't have a lot but i do have enough to fill my studio. I'm not bringing big furniture however. besides books and clothes I have my daughter's toddler bed and a rocking horse from her great-grand parents. In the end which would be cheaper and/or smartest. I've called around but would like some real life experience to back up my decision.
