I personally utilize Craigslist for a large portion of my part time online business. I have been posting ads to Craigslist for over 8 years and have a well rounded concept and knowledge of the guidelines that must be adhered too for successful postings and results.
I own and operate a medium sized Office Automation firm of which I use to post ads daily and receive a great success rate for securing positions, Everything from simple posting ads, retrieving data, prepare and or edit resumes.
