need facebook likes for multiple fan pages $$

Is there an efficient and cheap way to get 50 likes ++ per fan page if you need it for a large number of different fanpages? at fiverr most if not all sellers will just send to one fanpage at the time and 5$ is pretty expensive if you want it done on a large scale.

I just need 30 or whatever it is per fanpage in order for facebook to give me a permanent URL I can build links to.

help appreciated whether its a service you recommend, a service you offer yourself or some sort of bot that I can buy
