How to make your ideas work.

Gob Gob writes: What do you do when the app has grown with you? I have written a business app for a growing multinational business services company. It is very effective in its space and selling the software could be a very viable business (which I am able to do with the company's full support). The problem lies in the fact that the code has grown with my skills. What started as a hack around a PHP hand-me-down has become the CRM, Invoicing, Payroll, Web Site, Email, SMS, etc, etc all in one. The problem is that this application has some very crappy code and no one can support it but me. I do not want to drop my focus on new features and delivering to the user base to do house work on the code but I can't really see me getting the software to market when I am the only one who can understand the amateurish components which comprise some of the beginings of a very large app.
