My point is that Ukrainian sites charge less, because they hire qualified folks from India, Pakistan and Nigeria, that is why the price is lower however quality is not bad. I've had some experience working with Ukrainian sites and I actually was satisfied with the result. I also co-operated with US sites and frankly speaking result was the same but the price was doubled.

I have found couple sites which provide jobs even during low season. When there is no job I'm browsing through forums and read comments about companies which run the same business.
