Help with selling beats online

Hey guys I'm new here.
I'm currently working on a website for my music and was wondering how do I render wav stems for the wav trackouts purchase?
I know how to render them but my main problem with it is the sidechaining.. Say I have a sidechain on a certain sound, like an 808 and the kick, when I render the 808 wav there is no sidechain cause the kick is muted on that wav.. Can't get an idea how people do it..
