AD posting in Classified website like craigslist, kijiji etc

I am looking for someone to help me post ads in major classifieds websites on an ongoing basis. I will provide HTML, Graphics and text ads, you job is to post ads on site. Initially you may need to register accounts with sites. **Prefer someone who has already done that so that I do not have to train and also do not have to teach where to post. You should be aware of major sites.**
