There, at least in Colorado, is a really easy way online to make yourself into an LLC or whatever you want, but I think that doesn't really matter unless you're like a multiple-person business because it shields liability in some way if you have a business.

You could make a trade name. I made that a while back for my DJ business, haha. It was just like 20 dollars or something in the state of Colorado to file a trade name. Making a trade name would probably be the best option, but if you don't care, it's not really necessary. I don't really know the legal implications of this.
