Craigslist poster

Hello coders, I need someone that knows the ins and outs of craigslist posting. I'd like an ad designed with some text and an image. Then I'd like this ad posted in only 30 major cities in the US, so it's not a huge job at all. Whatever is required to keep the ads up daily then do so within the rules of craigslist. In the ad I will be offering my audio recording, voice over, editing, and video editing services. As well as converting LPs, CDs, and cassette tapes to digital format. In your bid explain how you will post ads and keep them please, thanks!
