I've got a huge headache (both figuratively and literally)

I woke up this morning with a migraine headache and could hardly get out of bed. After going downstairs and having breakfast I took 2 Advil I went back to bed.  When I was sitting in bed I started to play around with my Ipad, and I started listening to some podcasts.  I listened to 15 minute craft website tips and she recommended getting the domain name for your website.  So I went to godaddy.com and tried to register craftsbyknight.com and it was taken.  I called the number provided and the guy that owns the site answered and he bought it for his wife whose father is starting a business by the name of, you guessed it "crafts by knight"  I gave him my contact info and he said he would ask his wife about selling me the page.  I am kicking myself right now.  I should done this first before choosing my name, but now I don't know what to do.I figure I have a few options, the first one is to wait and see if he is willing to sell me the page.  I am going to do this for one week.  My second option if I can't buy the domain name from him is to change my name.  I was thinking of the name "Jewelry by Knight"  but this would be a huge hassle, I would have to create a new fb page, gmail account, pinterest account, and get a new etsy store.I could register "jewelry by knight" before someone else gets it, but I don't know what to do.  Does anyone have any advice for me?  I don't know what to do.UPDATE: craftsbyknight.net was available, so I am not going to change my name, I have craftsbyknight.net and blog.craftsbyknight.net as well as an email address, which I will set up later.  It will all be up by Sunday.  I can't wait.  the .net will forward people to my etsy store and blog.net will forward people to my wordpress blog.
