Needed help to sell a USED LG ARIA -130 CORPORATE PHONE SYSTEM WITHIN AUSTRALIA

Needed help to sell a USED LG ARIA -130 CORPORATE PHONE SYSTEM WITHIN AUSTRALIA This is a serious piece of hardware I picked up and I am not sure how to sell it or ship it or ship it, it includes 3x phone handles.. They cost originally $5,000, but now sell for between $300-$500, I am hoping to get this price. Ideally you will be able to sell it within my state, to a hotel, office, suite,company, phone specialists etc. Please set the sale up and do research on the hardware system and I will give 10% of the sale, ideally line up a buyer in my state or city, so, please bid, on your price, you think it would take to successfully line up a buyer.
