Hello,
I am Krunal K. Doshi from Ahmedabad, having 8+ years of experience in web and windows development. We have developed many static, dynamic websites and desktop applications using Microsoft Technologies and PHP. We are a team of 5 experienced programmers, whose experience range from 2 to 8 years.
We have gone through your post and understood that you are looking to enhance your existing application by adding user management to it. You would also like to add rights management along with the above changes. Also you want to add functionality where user can share document with other people. Before proceeding further we would like to review your existing application so that we can provide you with best quote. Our current estimation is based on assumption which can be reviewed once we receive further information.
Let us know your concern/s if any so that we can quickly move ahead on this project.
RegardsrnKrunal K. Doshi
