Sorry, do you mean facebook fans or followers?

The best way is promote with facebook ads, but you will need to spend some budget.
You need to research your audience target, setup clickable ad then try and test to see the best result.

But if you want to cheap, just keep update your status with valuable information then asking people to like and share your status. Time consuming but soon you have very active fans/followers, you will get big success.

Good luck with your effort

By posting in Groups, you'll be establishing yourself as an expert. Someone who people look up to and trust to solve their problems. Once they trust you, they won't hesitate to join your page. Once you have a good reputation, you can request the group admin to promote your page maybe pin it for a day. He may or may not charge you for it.

you'll need to run ads as well if you want to increase your likes. Moreover you should also put the like button on your blogs and websites. Running contents and giving free give aways will also help you get you traffic.
