Wanted: Personal shopper in BRAZIL

I am interested in buying some books from online Brazilian stores. However, I live in the United States and do not have an address in Brazil or a CPF, so they will not sell to me. So, I need a personal shopper who is living in Brazil and who can buy the books and ship them to me. I will provide you with a list of websites where you can buy the books. The total cost of the books + shipping to your address in Brazil is approximately R$75. The total weight of the books will not exceed 1 kg. (It will probably be much less than that.) Assuming a weight of 1 kg, the total cost of shipping to the United States by Correios EMS is approximately R$75. Before you buy the books, I will set up a milestone for 100% of the cost of the books + shipping, plus some extra for your service. If it turns out you need more money, I will set up additional milestones. (For example, if a certain store does not have a book in stock and you need to buy it from another store that is selling it at a higher price, I will pay you the difference.) Because there is some personal information involved in this project, you will be required to sign a non-disclosure agreement.
