I think my bid is the only one that actually has some sense in it ... it's a big project, I know. That's why I said 60 days. Out of that, about 15 to 20 will be research and study. Then, 30 days of development and 10 days of testing. After that, the alpha version will be finished. Now, from here on is a long-term relationship since bugs will come up (they always do). But first, let's develop it and then think of the rest.
Oh, I almost forgot. I am developing right now another project, about the same size. It's a personal project for a small business I would like to start next year. So yes, I am up to the challenge.
