A little advice...if you don't want people coming in for one 2" sticker then stick to the website and don't open up a storefront. Keep it by appointment only. Definitely get a laminator. I think you could get away with not doing installs. I don't do any sign installs but I sell a crap load of them. You could join a B2B group or the local chamber of commerce. In my town when you join they put a post on FB and they send an email out to all the members about your new business. It was $25 a year.
Be prepared for a lot of calls for small jobs and don't get caught up in that small stuff. Have a minimum and stick to it. The biggest time waster when dealing with the public is the small jobs and the people that want those jobs have no problem wasting 20 minutes of your time trying to convince you to do them. And they tell their friends and before you know it, you have 100 of them banging your door down. Have a minimum and stick to it.
