Question for Win Express (Yangon-Kyaik Hto-Kyaik Htee Yoe-Bee Lin-Tha Hton)

I would like to buy direct bus ticket from Yangon to Kinpun on 14/11 and with return ticket on 15/11. How much is it and where can I buy it in Yanogon? I would also like to know where I will get off in Kinpun as I wish to go to the Golden Rock Pagoda.
