Divorce attorneys in Miami Fl

Can anyone recommend divorce attorneys in Miami?
Don't have any family or friends here; just moved in from NY, six months ago, after separating from my husband. Have with me two children, after having a provisional custody granted.
But, my ex wants to challenge that. That's why I need to engage a good lawyer... that won't cost me big money, which I don't have.
Have made some enquiries, based on the Yellow Pages listings. But, nobody will offer me a free initial consultation, and their fees start from $120 per 30 min. It's a lot of money when you're a single parent of two teenagers.
Anyway, don't want to risk paying a lawyer that won't do his job honestly, and will try to maximize his fees. If you've any experience with an honest lawyer, whose charges are reasonable, let me know.
Ciao! Sam.
