I'm not sure why I would need an attorney. It seems pretty cut and dried. Do a search to see if the name or anything similar is being used. If not, fill out the application, pay the money, and done. Am I missing something? Help me out here.
I don't think "reserving" your business' name is the same process as an actual trademark. DoggyMama and I very briefly started a lawn care business and went through the process that it sounds like you're describing. I think trademark/copyright law is a different animal.
I'm not talking about an LLC. I can do that also. I'm talking about trademarking the name and logo of my product line.
