15k a day keyword domain

[wxdqz]

hey guys i am just wondering would it be worth it to buy a keyword domain name that gets 12k searches each day. the name is basicly blahblahblah.org and the keyword is blah blah blahwould this pretty much guarantee a page one rank on google or will the .org hinder it a little bit? I guess buying the domain name at 8.99 wouldn't be a bad investment anyway?I'm pretty new to this, so any help would be appreciated. I hope this is the right section if not please move it.*messed up title supposed to be 12k
