Argentina Chile and Peru

In November I am planning to be in Lima. I wish to visit Iguazu Falls and Cuzco. I have 10 days and a very tight budget. The flights to BA are very expensive. Is there a way I can visit these places in the allotted time on a budget?
Someone metioned a bus but no prices are listed on their site...
LAN does have cheap fare to Cuzco from Lima but from there how do I get to Iguazu falls.
I am an experienced traveler and have lived in a 3rd world country for 5 years, I can take any form of trasportation it doesn't bother me.

Lima - Iguazu - Buenos Aires - Lima in ten days? Madness. No matter what form of transport you choose, you won't have enough time to get anything out of your trip. Best pick a destination closer to Lima; plenty to see in Peru as well.

I agree with the previous post, you are to ambitious. You can do it but you will have to make it by plane which is out of your budget as you explained.

I suggest to focus on Peru, there is a lot to see around Cuzco area, including the Amazon jungle.

Have a safe trip,
