I am starting a new website.. advertising multiple things .. and could probably change the content of it depending on what works...is there any sites to help create domain names ?

to help create domain names????
NOt sure what you mean by that.
You have to choose yourself domain names. Use your imagination and come with good ones. Most of the great and easy to remember domain names are already taken.
Once you come up with a good name, you have to register it.
I don't think there is a site that help to create domain names.

That's so confusing. You mean you want to register domains names? Than you should use a domain registrar like Namecheap or Godaddy.

i think he means sites that help you think up a name for your domain name, like a domain name generator or something, try http://www.nameboy.com/ seems like (kind of) what you're looking for mate....
