audio video content

i currently organize conferences where people physically come and listen to a lecturer. i wish to go one step further: audio &/or video record those conferences and have their content made available online (chapters). I don't know much about videos online - i assume streaming is the best answer to what i wish to provide. I will do the video/audio capture myself. Basically, visitors will access a checkout purchase page in my current website (this part of the programming is handled by us in php - mysql); once they have paid a fee, that's where you come in: visitors have access to a page that includes info about the video and various chapters (video title, chapter titles, durations, player window, ...) for a given period of time, say, 2 weeks - so they can watch any of its chapters as many times as they wish for 2 weeks. after that period of time, the page becomes obsolete (it will say 'your subscription to this conference has expired - if you wish to renew, click here - other conferences you might like: .... ') - your job will also be to explain to me where & how i can best store the videos (server) at a good rate - explain the logic i'm looking for a freelancer who really masters these concepts, so the creation of this will be really fast, simple & obvious we have all the dbs with the customer information, ... and we can handle creating new dbs under your recomendations to store necessary page access info, page references, etc. thanks
