Trueform Made roofs and crates for Las Vegas, NV Internet

Built Bus shelter roofs for a las vegas project they hired our company for.  we also built crates for trucking them to las vegas.  there are also 3 other companies that they did not pay. we were all given purchase orders.  we were paid for all the tooling but were never paid for the roofs. las vegas paid trueform and they deposited the money into their bank in the uk and closed there office in new jersey. we are talking about 1.5 million right now with all the interest. I have all the emails and purchase orders so do the other companies. what they did is not right to any of us.  they need to pay every one involved in this project.  this goes back to march of 2010.
