I am a fulltime freelancer and I personally have used CraigsList for various reasons. I have helped a couple of friends post items they were selling on CraigsList. I noticed you stated that you would not except bids unless they knew how to use CraigsList. So, I will merely go through a few steps to let you know that I can do this job so, one would first select the city and state in which they wanted to target, then you would click on post to classifieds, next choose a category, then select a sub category then the city, enter a title, price and location. Enter a description, email address, click on add/edit images (if you are using them). Accept the terms of use upon doing so your will receive an email in which you would simply follow the instructions.
Please let me know if I can help you with this project?
Thank you.
