we did a wedding at home (well my brother's place), I gave my bridal party material for their dresses (bought wholesale) & they made their own, the boys were just in black pants & white shirt (including groom - but he had a waistcoat made out of same material as my dress). We used one of those spit roast places (they actually did a better priced wedding package than if we'd done the bits separately), we also hired extra chairs/tables off them. We bought the alcohol on sale (and got a discount on top of that for the bulk buy). One of my best friends drove me there in her car, she also drove us all home afterwards, we didn't do a hotel that night because we couldn't see the point, we just went home to our own bed. We found a photographer who had a great deal for the photos & we got them on CD plus an album - I've just printed additional copies since then for friends etc. Most expensive thing for us was my dress (which I've worn since) and the bonbonieries (individual hand-made glass african animals).

One of the best weddings I've ever been to was actually an engagement party in which they went and changed half way through the night and got married, none of the pressure of planning a wedding.

Good luck with it all, have fun!
