Need a bot to post multiple ads

I have several ads that I have created in kijiji.ca.? They are posted with others by time of posting...so after a few days, the post drops down in the list.? I need a bot that will repost the ad every XX hours.? If I have several ads, I can designate which of the ads will be reposted (i.e. application can handle several ads). So the ad and the photos associated with it must be re-posted.? If necessary, I could put the photos in a predetermined directory.? There is no formatting of the ad content except for paragraph and font...its all text otherwise...and some photos. I need to be able to designate how many times it will be reposted, as well as the ability to "kill" an ad I don't want reposted anymore.
