Assistance with payments testing (Chile)

We represent an international e-commerce company, and we are looking for someone to help us with testing the company's payment systems. Initially, this is a single piece of work for which we will pay a small fee, but there is potential for future work if we can find a reliable person. We need someone who is currently in Chile. The work consists of the following: - Using our test systems to generate a payment voucher (15 minutes work). - Going to a ServiPag outlet to pay the voucher. - Reporting back to us on your experience (Was the payment easy to make ? Did you encounter any problems ?). - Providing us with a scan/photo of any receipts provided by the outlet, and preferably some photos of the outlet itself. This is a relatively simple piece of work, but we obviously need somebody that we can trust. The person will need access to Skype/googletalk so that we can send them the necessary credentials to access our systems.
