i know this is way off topic and i don't mean to be patronising in any way but you appear to be a young man in a huge hurry to get to an "ideal world" of luxury and happiness. Personally i dont think the world works like that.
If i was you i would concentrate on enjoying my new relationship for a whole lot longer before getting married. Your fiance comes from a completely different culture from you and a few extra years getting to know, each other, each others families and each others cultures would be very well spent. I think you should spend this time enjoying yourself and not to worry too much about money at all.
What you're planning is not easy. You are trying to juggle a new relationship, a new culture, a new wife, a new baby, a new job, a new country, a new extended family all into one very tight time frame. This doesn't make too much sense.
Slow down.
