There some tool which can increase like.you can check add me fast, this tool can generate some like..but after 20 or 30 likes you need to pay to increase your like
If you want to get more and more likes then I recommend you to buy atleast 1k likes from free facebook likes or you can use fiver, after attaining 1k likes start promoting your page in your friends wall and other communities. As your page already having over 1k likes then people usually like pages with numerous no. of likes already.
the basics is as stated before, add quality content, then ask people to join on wall of related fanpages with lots of fans, it will be hard and slow, but if you really want to do it this is how many pages are created
