I am working on a project that has grown to a decent size, and I am the only developer. We currently don\'t use any version control, but I definitely need to start.
I wondering why you had chosen Subversion? If your project is not using any vc, may be you should consider to use Mercurial or Git either.
Their stronger point is that they don't need a central repository, that means that your programmers can checkout your project, go to their home, work (without having to have a connection to your servers), and the next day come back to the office and sync their repositories.
If SVN is not a mayor requirement, i recommend to consider any of both dvc systems.
