Well Hello!,
I have some kind of thing for fixing-updating-adding stuff to existing websites, learn about other people's code and stuff, so that's why I bid on this project, but before, I also want to ask what do you really want?
You said you need that system to meet your requirements, but what are those requirements? because as you sure know, it could affect the time it will take to be done and the price, which is kinda fixed at the moment =).
Hear you later!.
