Help! Is this Okay to do to start a business?

I know I want to start this business, but I have absolutely no money. I was thinking of just starting with my name, and not yet registrating with the county until I had made some money to cover the cost of the name and taxes and insurance. I should be ';legal'; within three to six months. Is this okay to do or will I be reprimanded? Will I have to pay back taxes for the company? It is a consultation/service company dealing in Real Estate.
