I have been a webmaster for around 12 years, but only a coder for 2.5 years. I have been a single man team coding projects for myself. However, I am noticing a market for the type of apps I create and I do not know where to begin with what I need to do to implement a system to sell my scripts on a monthly fee basis or a per domain basis. I have been creating web apps with codeigniter and although I don't mind a client seeing the framework, I would prefer hiding these files or encoding them so I present myself a little more professional.
Since I am a single man team, I never had to worry much about version control, encoding my code, and licensing.
I would greatly appreciate someone taking the time to put me on the correct path of how to accomplish a solid system for controlling and selling my web applications.
