Thanks a lot for the project posting, i have gone through the requirements and also i have checked the attached document. I have not filled the hours in, because this project is more of a fixed cost project rather hourly. But if you still need let us know. We already working with high end enterprise level clients across US, UK, Canada, SouthAfrica, Australia and Saudiarabia. We work mostly on business level applications like one you want to get developed here. As precise discussion about the project will be helpful to estimate accurate time and cost.
