I wouldn't get to hung up on being "scabable" if I were you. Just do it and worry about that later if it becomes an issue (which it probably won't, plenty of sites are successful at what they're doing without having to many troubles in this area). Oh, and learn to use source control (Git or Mercurial or similar) if you haven't already. When you break something on your site and don't notice for a bit it's pretty important to be able to look back through the code history to find out where it all went wrong :)
