My Friend,
That is such a simple question,... with a simple answer. If money is no problem to you, then make a date with her and go to meet her. Make it in such a way that she feels safe at all times. The agency can help you set it up if she is not sure of you or what you say. The main thing is consistency in what you say, say it and mean it. If you have to go there to show her, then do it. If you can't find a way to do this, it's useless to go any further until you can meet her wishes. You'll know more when you set up the date. If you can't do it alone then ask her if the agency doing it is okay with her. Her safety is a big factor. Best wishes!
