Also we got our alcohol through the greysonline auction website where you can get wine and champagne etc by the case. With beer we grabbed a case or two a fortnight for a couple of months before the wedding and just stashed it in the garage. Oh and for the champagne and wine glasses you can hire them from Ritchies for free (you just pay a bond and any breakages - we broke one in the dishwasher) Didn't seem like any expense that way for either the beer or glasses. All up we would have spent about $500 tops on alcohol and had a choice of 2 whites, a red, different beers and both white and pink champagne. and we had heaps left over (still have stuff in the garage!!).

I also found the catering website that we used if it helps to give you an idea. these people were awesome and unlike most ****tail parties where you never feel quite satisfied everyone said they were stuffed at the end of the night. They also do buffet style catering as well.
If you google eatathome it should come up.
