openvpn custom script

Dear Partner, I want to hire someone for a small script for my openvpn server, which i am maintaining and able to connect remotely from any machine and clients are using internet services from server's pubilc ip, successfully. Now i need a customized routing on my openvpn server, that There are two internet connections on my Openvpn server, one must be used for the purpose of providing openvpn services, while the other connection must be used for providing internet sharing from server's ip. Please note that the first internet connection which is being used for inbound connections of clients on openvpn server, must not be shared to clients for internet services,,, but the second internet connection must be shared with openvpn clients coming for services on openserver. There are some more small details which i would like to discuss once you successfully bid this project. Regards,
