What do you think about my idea?

my idea is a advertising platform for facebook : I want facebook page owners to make money out of their pages : they submit their pages for advertisers and advertisers come search the submitted pages they choose one then the page have the submit a link to the advertiser every day twice for example(I am still thinking about this part) or the page give admin access to "adsbot" so it can share by itself then the page get paid monthly/weekly/per click (I am still working on this) so : 1 - is it profitable ? 2 - is there any competition right now ? 3 - should the page be paid monthly/weekly/per click ?
