I think the name also depends on how many people are going to be in your firm. Are you the only one in the firm? If so, I like "Structures by Robert".
If you plan to have others in your firm, then I think Michael is on target. Remember that everything is on the Internet now. If you can find a creative keyword, then you should probably use it. I recommend using nameboy.com to find unique combinations. Just know that sometimes nameboy says the name is free when its not.
Nowonder you talk that way, You are a SEO coach and mentor and I believe you. you are right about choosing the right keyword.
