C++ Linux/Unix PAM guru

Hello folks, Please read the entire work description before you submit your offer. My company built PAM that works with two factor authentication platform that we developed. The PAM works great while using SSH. You can download our SSH source code from here: [login to view URL] Step by step instructions on how to install/configure SSH you can find here: [login to view URL] Currently, upon SSH login the user will see the following authentication selection list: “Using keyboard-interactive authentication. Welcome! Spriv Login... Please choose your authentication mode: 1) Adaptive Risk Based Authentication 2) TOTP 3) Allow | Deny Single 4) Two Way SMS Selection [1-4]:” The user can select a number (1-4) and the two factor authentication method would take place according to the user’s selection. We are looking for an excellent Unix/Linux ninja to design and build a PAM for SUDO and write the documentation. Unlike the above SSH authentication, while in Sudo authentication we want to have a pre-defined configurable option (1-4) by the System Admin, which upon sudo authentication the two factor authentication will be selected automatically as pre-defined by the system admin – and without presenting the authentication selection list to the user. The user should be able to authenticate via our Two factor authentication upon SSH access AND upon each sudo command. so we may need to have one PAM for SSH and one PAM for SUDO. Thanks, GH.
