Looking for a marriage agency in Florida

I'm currently looking for a foreign marriage agency in Florida for me and my fiancee. She's originally from Cuba and I want to make sure that things go smoothly when it comes to the legal works. I've done some research and if I'm being honest I think it's too complicated for me to process on my own. My girlfriend has had her working visa for a while now, a pending application for permanent residency. We don't think it'll be approved by the end of the year yet. So we decided to seek 3rd party help so we can process our marriage arrangements faster. Can someone recommend me to something please?
