Not being able to book the wedding is not a problem, your statements and possibly a couple of further ones from persons that know you will suffice.
Physically not having met is going to be a problem, I would not advise making a spouse application without having met - it is highly likely that it will be rejected.
Your options are the following:-
1. She comes here on a visitor's visa so that you can meet. She then returns home and makes the fiance visa application from home. She cannot make it here if she is a visitor, she must return home I'm afraid.
2. You go out there to meet. She then makes an application for a fiance visa as she will then meet the criteria which is problematic at the moment.
3. You go out there and you marry. She then makes an application for a spouses visa by using form VAF4 (available for download from the UKBA's visa website). In reality this would be the cheapest and probably the quickest way forward as only one application would have to be made. With the fiance visa it's two applications; one for the fiance visa and then a further application for a spouses visa once actually married.
Sorry it could not be simpler, it's a fairly common lament of people wishing to make immigration applications.
I hope this clarifies, if so please kindly click accept. You will be free to ask follow up questions.
