We are at 100 hours now. Letterlicious will be submitted at the end of this week. We have all the functionalities you are describing as well. Pretty much a fully loaded app. Working on a total budget of 5000 US gives us a fighting chance to make our money back.
You seem to have the development process mastered to absolute perfection!
Do you have any advice for people in the dev community that haven't streamlined their development quite like yourself? This post was supposed to be help other people in the same boat that we were/are in, not to shamelessly plug games. Since you criticized our development time, would you be kind enough to point out some of the areas where we went wrong and suggest how/where we could improve?
