Girls sz 7/8 uniforms for North Lakeland Elem

Well be starting north lakeland elem in a couple of weeks, currently Target doesn't have school uniforms. I'm going to check craigslist, id hate to pay full price, so I thought id check here first. Forest green, white and navy blue polos or button downs, khaki bottoms...anyone have any or know of a fantastic place? Ps, I've scoured the thrift stores too =(
