Angela, I do think you have a difficult issue to work out - it seems your fiance is steadfastly wanting a simple, inexpensive affair, and that you want a church wedding with the beautiful traditions that are involved.
If you had a wedding at home but with a officiant of God presiding, would that be a compromise you can live with? There are many ways to make such an event glorious and special. And as Niki said, it can be done on a limited budget.
