trying to find buisness ideas

I would really like to figure out some type of business that I could start up that would use web and social networking sites as a foundation.  Something like managing the online personalities for businesses/bars/restaurants and the like.  Wonder if there is a market for this? And if so, how much one could charge a month for something like that?  Creative Network Solutions for a base name maybe?  ok, I am just thinking out-loud but I am sick of looking for non existent jobs, that is for sure!
