The facts you state may implicate copyright and trademark law. Your business plan is entitled to copyright protection regarding the creative portions that you authored. Facts cannot be protected under copyright, but a selection of facts and conclusions based on the facts could be protectible. However, before you enforce a copyright, you must register it with the United States Copyright Office. If you did not register the copyright before it was copied, you have already lost the right to ask for attorney's fees and "statutory" damages (damages that don't require proof of actual harm to you). If you have trademark rights in a term that he is using in his domain name, and he is offering goods/services that compete with yours, this could be trademark infringement and cyberpiracy. However there are a lot of facts to determine whether you have an actual case under either of these theories.
