Hi Deon,
I would highly recommend both of Richards sites. I have worked and also hired on oDesk and they are very safe for both parties involved. I have carried out work on Elance too but never hired.
Fiverr is extremely cheap and good but it can be like finding a needle in a haystack. When searching in Fiverr always click on the rating and find people that are start rated and have had the job going for some time
