Great Services?

I tried to find a good writing service over the past week and I am quite overwhelmed. I contacted a few sites that I found, but was discouraged by online reviews (seems like all sites are lampooning each other) and by the fact that everyone I was in contact with were people of clearly Indian roots who called themselves "Scott Blake" or "Amanda Winters". What is a GOOD site for finding good writers? I assume they will be a little more pricey, but at least I will get what I want?! How do I find exactly what I need? Any recommendations? Factors to look at?
