some vendors slide over a contract, expect a signature & they're on their way. i highly recommend reading between the lines & making sure you're the ones coming out on top.
one example: some bands have different lead singers they rotate depending on availability. you might have picked a band based on one singer and have a different one show up the day of! see if you can get the band to put the name of your desired lead singer in the contract. try to make it official.
any other contract/negotiating tips?
