What is the cost of a Georgia uncontested divorce?

I am trying to plan for the upcoming filing of my uncontested divorce. I need to know what the costs will be and whether I will need to pay a lawyer. I have found the cost of the initial filing fee online, but I am unsure what other costs may be involved. One of the requirements for the uncontested divorce seems to be the submission of a marital settlement agreement stating the terms that my ex and I have agreed upon. This is where I am very uncertain about costs. Is this something we can draft or something we need to pay a lawyer to do. If we must have a lawyer, what is the average cost for the legal fees for the settlement agreement? Are there any fees due at the time of the final divorce? Is it permissible for my ex and I to split the costs equally?
