I got a yard guy to spray at work last year.... We had no grass and it was a sod yard 7 years ago when they built the place.....it had never been treated so when I started I got a well known local guy to start treatment. He killed everything but the fescue last year and killed it this winter with his roundup treatment. It is going to look great this year. Heck, it looked awesome at the end of growing season last year. He does 7 treatments a year. I finally told him he could do my yard too. I spend a lot of time and money on fertilize and preemergent and it still doesn't look good enough for me. He will have it looking better and it will run me about the same as having to do it all myself.
