DIGITAL FAX SUBSCRIPTION WEBSITE

Need a developer to establish a digital email fax solution using the open source code from efax(Http://[login to view URL]). I would like to utilize the open source code to establish my own online business for sending and recieving digital faxes on a subscription based service. I would like to leaglly duplicate what efaxes capabilities are and upgrade by providing a nicer GUI. Once the site is established and running I would like to integrate a mobile application for celluar phone usage and forwarding of email and attachments stored on mobile devices to physical fax machines.
