Seems many facebook page owners are headache with the promotion of their new facebook page because lack of visitors and "like".Why not we help to "like" pages of each other and promote together? I think it is much better than buying "like" from some "like" sellers. My facebook link you can see from my signature or from my contact details in this forum. Like my page and leave your link and I will like yours back.
I think this is what you are looking for its is mostly discussion, but you can add your link there and others will exchange likes when they see it posted there.
