Greetings Car ER and welcome to the forum!
I don't pretend to know as much as a lot of the pros on here but some things i might have some comments on.
1. A banner program is basically a organization or network of shops that represent a certain "banner." For instance if you have a NAPA auto parts store in your area you may be eligible to sign up for their program. Some of them are free others there is a small fee. You are entitled to all the discounts, programs and benefits that the banner program provides which normally includes discounts on insurance, payroll services, parts, warranty services, business and tech training, marketing, and other auto business related stuff. You may or may not also have to hang a sign stating you are say a NAPA auto care center. It is worth looking into. I am a Bosch Service Center and there are some of nice perks that go along with that.
2. Your first year of any business is going to be rocky unless you have a bit of luck and a lot of detailed planning. Researching and writing up a business plan as well as executing that plan will save you years of pain and hardship TRUST ME. Look into and learn about marketing heavily.
If I could make any suggestions, a more visible sign and possible a larger sign would work great for you. You can hardly see the sign with the combination of colors you are using which blend in with the building color. I would assume that it would be hard for cars passing by to spot you.
Good luck with the business!
