Fiverr.com has a lot of good graphic designers. I had a few images done via that site.
To get the best logo you really need to research other designers and the work they do and find someone that fits the style you want.
Fiver doesn´t give designers very much compensation for their work so you wont find very much talent there.
If you did want to check out a logo design competition site that is similar I would suggest 99designs
I tried Fiver and was not impressed at all. Its challenging to find a good designer on that site. At least for the typical small amount money involved. I ended up using Deluxe.com (not the checks) try searching Deluxe logos. They are very professional and will work with you until its right.
Hope this helps,
