If ya lived in raleigh heres what ya would do. Buy some round up and kill everything in sight, in a week or so fertilize the dead stuff, water if needed and if anything green pops up again kill it with roundup, repeat till nothing is coming up, might take 3 total weeks since its weed seed that doesnt die with roundup but the fertilizer and water will get it to sprout. Once your sure its all dead rent a power seeder and put down a good quality fescue, rebels or any other blend is great. Fertilize with seed starter, water and by end of sept your lawn will be an award winner. Followup by winterizer at thanksgivin and spring fertilizer no later than valentines day. If ya get any weeds after that should be able to control with spot weed killers that wont harm the grass.
