Chan tours would be about 460 baht and the trip udon to bangkok is about 8 hours (the other way more like 9) depending on the stop time in KK and traffic. Udon leaves between 8 am and 9pm almost every hour not sure about Nong Khai though the price from there is just over 500 and probably need to add an hour or 1,5
