There are two ways of getting website, either you develop by your own or you purchase it from Web Devlopers.
Managing website is not a easy job to do without having experience in it. It requires so much of technical and functional knowledge.
Since we do not sell any website, so I am not sure how can I help you out there but if you keep on contribution to RS then you can be eligible for the post of Editor of this website and can fulfil your dream of managing website.
Thanks and Regards,
