T, Florida has a certification process for family law attorneys. Someone who is board certified in Florida is going to have more hours, more training, more coursework in family law.
Also check out the American Academy of Matrimonial Lawyers and see if they have anyone listed in your area.
You want to avoid lawyers who claim they can help you with everything under the sun. Find a board certified lawyer who only does family law.
They should either not charge for the initial consult or have a low fee. Again this is to help both parties see if there is a fit. They should be able to give you estimates for the case based on certain factors (kids, house, retirement accounts, etc).
Don't assume that him buying a house is good for you. He may argue that it was property acquired after separation. Again something you need to talk to a FL lawyer about.
