wow, Venezuala , only 500 USD? I dont think alot of people are actually doing any mining there, unless they were wealthy before their economic crsis began. so If u want to start mining, move to Venezuala, and support their electricity companies?

This is purely if you are a stand-alone , as I can imagine if you are a business you can potentially claim lower electric charges (atleast here in Belgium)

Or if you got your own power source, you're having only to pay your gear :)
