Australian Importer List creation

I am in control of marketing at a Foreign Exchange company based in Sydney, Australia. We need new leads. Our target market is small to medium sized companies that are making foreign payments like importers. A good lead will be a company that is making between $250,000 and 3 million in overseas payments per annum. I am looking for someone to search the web for 50 leads. It will be up to you to determine the per annum amount of overseas payments... The required information is: - Name of company - Phone Number - Name of decision maker, this could be the CFO, Head of Accounts etc depending on the size of the company - Email of the company - Dollar estimate volume per annum You will be searching the web for websites that have this information and collecting it into an excel spreadsheet to be presented neatly to us. We are looking for someone to work full time for us to collect potentially thousands of leads so in order to find the best person, we require that you complete this trial of 50 leads.
