Do you have any cheap wedding tips?

my cousin and his fiance are marrying in june ‘09. they would like to have the catholic wedding and reception (inviting 250 people) in columbus, ohio (both families are from lima, oh). unfortunately, the budget they have been given is only $6,000. it sounds like a lot of money to me, but apparently it is not going to go very far. they are starting to get very stressed out and the wedding is still 1–1/2 years away! any tips or suggestions (esp. venues-that “don’t look like banquet halls”) would be appreciated!
