Honestly, you're probably better off making up your own name(s), unless those sell for REAL cheap. The data on your website and links you acquire from people pointing at you are what drive searches... And anybody that knows who you are (such as people visiting the retail location, or viewing ads) will go to the name regardless of what it is. If you already had the name in use, it might make some sense, but since this is a new venture... Just pick a new (and your own) name.
Although, making something easy to type and/or read is also a good idea to keep in mind.
I think I am, therefore I am... I think.
