If you must fly from OMA Southwest offers one-stop flights with times that work for $366.70
If you can drive the 150 miles each way to Kansas City Delta offers non-stops for around $346 though you can get one-stop flights on Frontier for as little as $241.20
Confirmed the Southwest one-stops $366 within your time limits.
If you are brave and don't NEED to make the trip, you could try priceline. A coworker recently got 2 RTs ABQ-CMH 2 days out for less than 50% of the lowest published 2-week out fare. Took her several tries (you can get more than one try by changing a parameter) but she was eventually successful.
