The world is interconnected but sometimes companies and individuals tend to look for people for hire in their own city, region, country or require relocation as if it was the 19th century. That is a reasonable thing to do if you are afraid of losing your intellectual property to a random dude in China. But I want you to think about this for a second. Most of the people in the world are with good intentions. That is the principle on which eBay is based. At the same time, you might get in more trouble with your IP with the local person if you do a poor hire.
