You can bring in large amounts of cash over the maximum of $10K. You have to have documentation as to the source (bonus, saving, sale of property or investment). If you delcare it then there is no problem (you will have to declare it in the US when leaving and also arriving in Peru.
I say, you should use tupacperu's credit card for all your purchases . . . . just kidding.
There are also money transfer services, such as PayPal, Xoom, etc. I would also check to see if any Peruvian banks have partner banks in the U.S.A. For example, Banco Nacional de México (Banamex) has had its own "California Commerce Bank" in California for years. And since Banamex was bought up by Citibank a few years back, it clearly has an agreement with Citi. Perhaps a similar arrangement exists with Peru.
One more thing: Peru has HSBC, and so does the U.S.A. If you have $100,000 or more, you can open a special account in the U.S.A. that will allow you access to many of those services at any HSBC branch in the world.
I don't know if this is helpful, but I thought I'd give my two cents' worth.
