well, I don't know... I guess you need to find out what affiliate agencies are available for peru and hopefully there is enough for you to work with. You could check these:
www.shareasale.comwww.linkshare.comwww.linkconnector.comwww.cj.comwww.90ok.comwww.niceoffers.comwww.dgmpro.comAlso you can search on google for affiliate agencies for your country. Usually these agencies send a check, they don't only use paypal.
Another way to make money online is with google adsense ads - you make a website or blog, google puts ads on your site, and every time someone clicks an ad you get paid for it. You can check google's adsense site to see if it works for peru.
Another possibility to check is ebay. They use paypal, but maybe not only paypal... also credit cards...
Or if you sell something like an ebook or software, you can set up a website that accepts credit card payments. Maybe there is a way for you to get the money in Peru...?
Do you have any special skill, like photo editing, writing, programming, etc? This might help but one would have to check it out.
