Geo targeted traffic prices? Looking for your opinion!

I am starting to sell gigs in fiverr but I like to first know your opinion for prices.
Traffic is good for alexa ranking etc. Analytics will show up this traffic.
There is 3 options, direct traffic, organic and referrer. I am looking prices for all.
It is possible to get traffic from other countries too but I think those are most wanted.
What are good prices for geo targeted visitor?
