Craigslist Posting

Can anyone create a software that allows a user to login into a system and choose a part or accessory from a digital OEM catalog and then take the stock photo & description from the catalog and post that unit on Craigslist and / or eBay in a very professional looking template? It will also allow the consumer to add a unique part or accessory if it is not located in the catalog. For instance they can add a Photo or Photos as well as their own description and get that in the same format to post to Craigslist & eBay. This would require someone with API knowledge and the were with all to map the fields correctly. Let me know`
