I decided I was going to do something similar just the other day! I read a zillion little articles for advice, over what ends up being a cliche name and what seems super original. I ended up stumbling upon this glossary of
Positive Adjectives.
So it becomes a game of 'pick a word that reminds me best of me that somehow looks nice with the other word that I want'. Double constants tend to help. For example 'Tenacious Tabbies Design' and then the end 'Design' becomes slightly unimportant. You can title your page with the full title but from there on out just refer to yourself without Design in the title.
I'm just a little worried you may end up sounding too much like a pet store, if you're not careful. ^^;
