Italy High School Spirit Flags

A few of us Gladiator Boosters would like to purchase spirit flags to run out onto the field with the players at the beginning of games, at halftime, and after touchdowns!  I got a quote from a reputable flag company and it looks like we will need roughly $1000.00 to purchase 3 -5' x 7' Flags ( I H S).  Any and all help will be vastly appreciated.
