Startup Idea : One good deed per day - Daily money gift

A website/ maybe app on which people that would like and feel like helping other people daily may subscribe, set a budget, and choose to spent that budget evenly on a certain amount of time(like 2 weeks), on chosen or random users. The budget will be used until it is finished, and only one person per day- either chosen by the payer or random chosen by the application may receive the money gift. Once the user which is payed has reached a certain amount - the money are released by the site's admins in his/her bank account/ paypal account
