In the past I have used design contests to get some ridiculously good logos for a couple hundred bucks. This was my favorite site that pooled talent from all over (lots from South America):

You need to give good instructions on what you are looking for and provide feedback during the duration of your contest to get good results (unless you don't know what you want and see what pops up).
I would absolutely not pay a lot for logo design until your business venture is successful. Going nuts on creative budget at the front end is a great way to burn through cash better spent elsewhere.
