I use Fiverr.com to buy the first 25 fans/likes to my Fan Pages (not Profile) so that I can get the vanity URL. After that, the best way to get more fans/likes is by using targeted facebook ads with good images. If you have a custom fanpage with good graphics you can build a targeted fan base.
My profile page is only for people I know personally not for marketing.
