Well if the Facebook page name is already taken then there is nothing you can do about it. You can always do a search for the name you want just to make sure it is still available.
You could make it slightly, slightly different, with a symbol or just add something like "your website name + fb page"
If you are lucky, you can try adding your business name after the slash after facebook.com. You will be able to do it in case someone else hasn't already taken it. For example in my case, anuradha.rao was already taken, so I had to compromise with anuradha.rao2 https://www.facebook.com/anuradha.rao2
My site is http://www.ranchandfarmlands.com and my facebook page is RanchandFarmLands.com just create a new page within your personal page. The you can toggle back and forth between the two. Or you can set your company page as your primary page and still go back and forth. Hope this helps. I'm pretty new to all of this and older. If I can do it you can too! Good Luck!
