Build a website for a little VPN company - read the details!

Hi! I have a little VPN service in my country. I have a joomla based website but I want a good, html5 based website. - copy the content from my existing website, just some page (9-10) - made an awesome design similar to expressvpn - made it ability to be multi language later I will translate it - user management - subscription - free, premium - manage subscription 1 month 3 months 6 months 1 year - Paypal and Borgun integration - my account: -- download amount in month -- upload amount in month -- ability to buy premium membership - a php file which checks user password and server info all these infos comes from post parameter from servers. You have to check are they valid or not and echo an OK or BAD. The servers will understand it. Count the users bandwidth every hour. And disable the free users if they reach the free 3GB amount. Make it very secure because we have receiving many attacks everyday. Must be mobile ready. -connect to a socket via php (the servers are open vpn servers you can connet to them via telnet socket ) - if an user reaches it's free limit give him a kill -uname. We have already got a website which is doing the same but it is based on joomla and we want a much better one. You can copy from the existing site, and sql queries. Id prefer a person who can script in bash too. Later we will have a good relationship it needed something. Thanks
