Hello

I work for the local health board, they have their own page on Facebook but wld like to add a smaller advert their page to do with stopping smoking. This advert can be simple or advert, it is better to take the reader to the page on Facebook to stop smoking. It wld like to add a widget that can take them making a quiz, say like advert.

Does anyone know how I can go about it? Also, if any, wld cost.

To search the Internet, even through a question and answer pages havent found anything.  The only thing that can be seen to create advert but we want it to be this specific page only.

Pls help, someone out there!!!

Thank you
