You can determine your costs by going to the USCIS.gov/forms. The fee will vary by attorney. You will need to inquire with individual attorneys. Fees will vary by the geographical location of the attorney, the attorney's experience and the difficulty of your case. Make sure any attorney you consult has experience filing marriage cases; especially in your situation.
Fees vary far too much to give you an estimate online. You'll need to do your homework and consult with at least three or four experienced immigration attorneys to compare fees, expertise, likeability, etc. And don't just consider cost when you make your decision...paying a few hundred dollars more for someone with more experience will surely be an excellent investment.

Immigration is complicated and the wrong action can have serious consequences. Never take action in your case based solely on general information like is offered here. Speak to an attorney who can give you specific advice about your own situation.
