Publicize for Local Dealers
Social Advertisements

Sell your own products or service

Are there real likes? 10 000 likes is quite small number for a Fanpage, You need to address they like your fanpage for what reason and then do bussiness on this reason.

If most of likes of your Facebook page are from relevant audience then it is possible to sell a good number of eBooks from there. But if the likes i mean the audience are not niche then its tough I guess!
