Hello. How are you? As professional developer, I can promise that I can deliver good result in a short time. I think we can add authentication when visit the website, so user has to login first, and can add role by user to have permission. I can work full time, 24hr/7, you can contact me at any time in your time zone. Once we work together, you can feel satisfy me and we can work together for a long time. If you trust me, I will do my best.
Hope your reply soon.
Regards. Nicholas
