Service Idea. Kindly Advice

Hello Roleplay gateway community,
My name is Arseney Sorokin, I've been a role-player and a game master for almost ten years and I require your help.
I know that a lot of you live a very busy life, whether it's the job, studies, or any other activity, not everyone has the time to arrange a role-playing group, go to friends, and perform all the required preparations to enjoy your true hobby - Role-playing.
Others are just living in locations where there are not enough role-players or no skilled Game Masters to run a truly exciting and indulging campaign.
These are the people I wish to provide my service to.

What is the service?
I wish to build a website with advanced role-playing features, meant to optimize the communication between the players, the Game Master and the core rules of the game mechanics, all done to improve the experience of my future clients.
In addition, I will be arranging player groups, based on the times most comfortable for them to play on and Game Mastering (At least until, hopefully, I will have enough clients to justify hiring other Game Masters).

What I ask of you is very simple - Advice.
*Would you pay for such a service?
*What payment method do you find most suitable for your current needs?
*What would make you believe in the integrity of the supplier of the service?
*On what core rules do you prefer the games to run? (D&D 3.5? D&D 4? WoD? Free Style? Anything else? Or maybe you are tired of the known set of rules and would prefer something new and refreshing?)
*What other things do you find neccessery for such a service to work?
Any advice would be highly appreciated.
I thank you for your time,
Sincerely, Arseney.
