hello, after looking at requirement, I'm confident about doing this, because we have done already one huge CRM for Matrimonial site. So, we have some experience on this. And the system was huge with totally custom scripts with security concern. But I can't give that link, because you know CRM is always confidential. If you would like to have a talk with us, then I will request you to send me the full specification. So that I can judge the proper time and bidding price.
Thank you
