Little packages forwarding

Simple mail or package forwarding service required. I live in Italy and would like to encourage and facilitate the online purchases from US. Unfortunately not all the sellers are willing to ship abroad. So, I'm looking for a US resident, with US address, who can receive packages (e.g. from [login to view URL] or [login to view URL]) and re-send them to Italy, via USPS or any other couriers. Strong willingness, reliability, trust required. All expenses will be covered in advance plus a fee of 15-20 USD per package as service reward.
