150 foot aisle runner

ok...so the aisle in my church is super-long! 150 feet to be exact! which means to order an aisle runner, the way i want it (monogram, names, date, quote) will run me around $250. i may be spending ridiculous amounts of money on stuff for the wedding..esp as it gets closer..but this is one thing i REFUSE to spend all that money on. so..i have decided to make mine myself. and, of course, i am having trouble locating an aisle runner long enough! the longest i see usually is 100ft. anybody know of any stores or websites where i can pick one up to start torturing my soul with this big DIY venture???

TIA!
