You should take out the text part and the teenager part and the slogan. All you need is your company name and phone big enough for everyone to see. Honestly people wont have time to look at you slogan when you are going 45mph down the road. And you honestly don't need to go "legal" the only reason you would have to go legal is if you are doing commercial properties. and then you would be subject to a 1099 from them. but if your going to mow residential you don't need to go legal and you can still have your name on your trailer. Hope it helps!!
