Well whatever you do don't pick 'The Roving Artist', I'll tell my dad and he'll be forced to sue you.
Of course, that won't happen cause it hasn't got anything to do with photography

(he's a silhoette artists... if you need a unique entertainer for weddings, coorporate events or just parties, he's your man, search "The Roving Artist in google! *ehem* I'll stop blatant advertising now... he's good though! Please don't kill me mods >_<)
hmmm.. names eh? well how about 'Photo's R' Us', if you want a big toy company breathing down your neck
OK I'll stop being stupid now! errrrmmm... well, knowing your name might help, why don't you theme it around your surname or something? In the end what really matters is whether you can make decent photographs afterall, you need to advertise and get yourself known by other small business's.
