I have a business selling bicycles, and I sell them on Craigslist as well as my own website, [url removed, login to view], which is based on php. I want a code that will automatically bump my listings that are not sold. Whenever a bike is sold, I will change the title of the listings to "SOLD". So the program just needs to check to see if the listing is renewable, and is not "SOLD" and renew it. I would like the program to run 24/7, maybe checking every 30 minutes?
I'm not sure how much this should cost, so let me know. I'd like it done ASAP.
