Having been through a similar circumstance (built a huge application by myself, which later grew into my job) -- one of the major difficulties you'll have is in finding anybody else that can understand your code. One of the hidden features for a framework, of any sort, is the general understanding of where things are, or can be expected to be. If I work within the conventions of Django, then when I'm hiring somebody, I can ask them if they know Django -- assuming all other things being equal, they'll have a much shorter learning curve ramping up to learn what I've built because they'll know, in general, where to look for certain kinds of things. If you intend to ever hire anybody, then I'd take every spare minute you have where you aren't coding, and get to documenting the framework you've built.
