You want my opinion?
1. YOU come up with your name.
2. Don't try to be clever, you want people to have a quick understanding of what you do!
3. It should be easy to read without any crazy font, clearly telling people what you do.
4. Personally, this shop is YOU, I highly recommend your name in the title.
I had a shop with a clever name, people never "got it", I had to list it in the yellow pages three different ways because people just couldn't get it right. "Bobs HotRod shop" is pretty hard to beat.
IF that is what you really plan on doing most.
I have done my fair share of studying marketing, just because I am a "student" of it, I just dig the science of marketing. And everything I have ever read all supports things told to me by a man who helped me with my first yellow page ad. He was a retired ad man and he told me the facts without wanting to make a sale, you know what I mean, he told me the truth.
One of the most important things is to not get caught up in the crazy notion that you WILL be known because of how great you are at what you do. Yes this is true, you will be, HOWEVER, at that point you don't even need a sign or a name! People will tell people how to get to you. You don't even need a sign on the building, the sign is for people who DON'T know you and what you do. This is why you need a name and sign that is very clear, simple font, no clever saying, BS, it should tell people what you DO in a glance. You are NOT the big boys who have a logo that doesn't even need words. A big yellow M (McDonalds) , a couple of round red circles (Target) you don't have the millions of dollars in marketing to make people see "TARGET" when they see that red circle.
It's like I always say, there is a reason why the street signs the state and city put up don't have cute and clever sayings, colors, art or font,
BECAUSE THEY WANT PEOPLE TO BE ABLE TO READ THEM!
Just a few ideas.
