I think these advices are very good. In addition to the above you can also put some links of your page in the others pages or account you have. You can also create a twitter account and write the same posts with a link to Facebook.
i found the best way ,.. We have a travel website where we travel in a land rover (bear with me) We found a load of Land Rover groups on Facebook and joined and started posting on them. This has given us 1000+ likes on our page. The best thing is, they are targeted useful likes So find a relevant group, or appreciation of whatever your page is about, join it, post on it, send all those people over to you! easy
Use Facebook Ads, Run Contest, Invite Your Friends to Invite there Friends to Like Your Page and Most Important BE ACTIVE Post Min or Max 4 Intresting Post Per Day.
AddMeFast.Com will work. But If you are able to get organic traffic, then it better than get likes from other non-organic way.
There is also an opportunity to add promos like cupons. You make an offer, for example like a free sample of your product, but to receive it, people would need to like the page and make the repost of your post and show it to you once they come to pick up the sample. This will engage more people, but of course if you are ready to bare some costs for that Interesting content will always keep people interested. Or there is always an opportunity to make a facebook campaign. I wish you good luck in this and I hope you will find the solution which works perfectly for you.

Keep posting content to your page so that it will always be refreshed with new information. It will also bury any past negative comments on your page automatically. It is important for your business reputation. This is an indirect way to deal with difficult people. You don't want others to see your interaction with them, so you keep posting content and your interaction with them will be buried deep within your page. Sure, your audience will still find them if they keep scrolling down your page, but most of them will not. While you do this, improve the way you communicate with your audience, so that there will be less trolls that bother you in the future.
