Website with fitness videos

I need a website done for viewing fitness instruction videos, they need to be viewed in flash (.flv) from a media server for smooth streaming, even when many visitors are viewing same time. Videos can only be available when customers have paid a monthly subscription, and viewing will be directly from the website after payment with creditcard have gone through. Videos will be fitness instructions video for people who want to do the exercise at home. Videos will be in aerobic, fitness,zumba and etc. I want the website to be done in wordpress.
