Startup Idea : Make your personal events , earn for you

I am a vivid traveler who wants to understand customs and traditions of different human races across continents. I would love to have a site where in one can publish his personal events and fix a price for outsider to attend the event. For added services like interpretation, lodging , food etc he may charge extra . There would eventually be a rating system to judge the person who is inviting and person who availed the service. This would ensure transparency and security.
