Startup Idea : A couple days jobs

I want to create a job board for freelance workers who only want to work a few days. such as sales promotion girl, event organizers, etc. The point is the system provide small jobs that can be done almost by everyone. This system is for people who don't want to be idle and unproductive. Everyday/everyweek you can get new jobs. The aim is that people can get a little extra money, meet new people who became their future connection.
