cell-phone-traders.com Scammed me out of $2000 Reno Nevada

Cell-Phone-Trader.com quoted me $499 for a 8 month new Iphone 6s which I thought was a fair deal. The phone was in a case for its entire duration. The phone was a home use cell phone only. I shipped the phone via USPS(with the label they provided). It took a little long for it to get there. I inquired about whether or not they received the phone. They said it would take a few days. In the meantime I also sold my Ipad 3(quoted $400), Iphone 6 quoted $330 and Iphone 5 quoted $128 in one package to the company(I thought it was legitimate at the time) It has been months. There website no longer works and they do not answer any phones/emails. I plan on filing a lawsuit. I appreciate being contacted by any attorney willing to help. I have all copies of tracking numbers and what not. This company is a complete scam and I want my items back or my money.
