Can anyone give me some advice about Lawyers?

I need to hire an attorney to get my Marriage annuled. I have noticed that the fees are HUGE!!! One guy quoted me 3 thousand dollars to file all of the paperwork. I have to pay others at least 100 bucks to get JUST A CONSULTATION!!!! I don't have this kind of money being a single parent and all. I don't know where else to turn, does anyone have any ideas on how to get lower cost services??
