I need help turning my Wordpress platform into a SAAS Application

Hey Legends,
Strange request but I have created a WordPress platform to serve as a one login ecosystem for coaches and I want to turn it into a SAAS system where it deploys an installation on payment for a subscription fee and restricts full root access to individual systems. I'm so busy doing course content and going insane I was wondering if you guys offer custom work, I could really do with some professional help to get this done. I basically want to clone my platform http://www.dotcomdisruptors.com or mutli site it so that it's easily updated across the board of clients. Please let me know if that is something you could help me with or if not could you point me in the right direction?

Cheers in advance
