Hi,
Sir if you need a software which 'd not be violationg the TOU of craigslist thn you must ask craigslist for a special permission, because they clearly state that the use of bots on craigslist is illegal,
well apart from that i do have a software for craigslist that may fit ur needs and obviously we can modify it together, to make it just as the one u need. i am attaching a screen shot of the software and m ready for demo any time.
