whatsapp to email bridge

hi, i am looking for a email & whats-app bridge. i want a tool to allow me & my friends (that don't have whats-app) to send and receive whats-app messages using email or hangouts. here's a git hub link to the concept, [login to view URL] there are a few unofficial open source whats-app app's. and there's a very good official hangouts API. i also want a web UI for my friends to signup to this tool (but i want to be able to verify every user before hes actually able to setup his account...). i also wane be able to setup pricing, etc. i could get a shared hosting (go-daddy or other) account, please let me know if i need windows or Linux server. if you are able to create this project (web UI, payment integration, whats-app & email and hangouts functionality, etc.) please post your offer. thanks
