First of all make an eye catching informative page helpful for viewers . Then post your Facebook fan page on different social networking or social media sites, it will help you to increase likes on your Facebook page.
I suggest you that don't use any tools/software to increase Fanpage likes.
You have to increase your friends on profile and request those friends to like your Fanpage.
Also you can join in different like exchange Facebook groups where huge number of members are available and share your Fanpage link there and request to like.
You can increase your Facebook likes by posting more interesting topics on your Fan page and attracting more visitors to your page. You can create communities and try out some debates and news to make visitors participate and hence redirect them to your fan page for more likes.
Periodically pay your fans a visit. Read their posts, like them and leave comments. Not only does that build relationships, but it also provides a way for their audience to visit your turf. If you grow your external presence, others will notice you, become curious, and come visit you. Also try Facebook like services, you can hire an expert from here, that expert can help you in providing facebook likes at a cheap rate.

In order to increase Facebook likes is not an easy task but for high profile person its a piece of cake. You need to interact with your targeted members in Facebook and study their behavior then provide them what they need and expectations.
How much do you want to increase likes? If it's about 100-500-1000, than it seems to me that only advertising on FB can have a great impact. An interesting content and images of high quality and even interacting with your targeted members 24 hours a day (attention, that could sometimes cause adverse effects) could give you, let's say, 5-10-15 likes in a week...
Ok, maybe I exaggerated , I played with small amounts increasing likes for start-up official page - it works. The other question is why and how convert likes into buying... Does it really matter on FB if it's a fan page or a business one?
