I am unfamiliar with webdesign and am using Ads Factory extension in Joomla. I am looking for someone who can write me a plug in if one does not already exist so that each time somone posts something for sale on my site, it automatically generates an unused alpha numeric customer number for them in the code id description box. Once the listing expires in xx days, I want that code to be reusable for a different customer. Also there are several small issues with the site that I need help fixing such as being able to charge a different price based on the catagory chosen. Ads Factory shows credits to buy and I am sure you can change it to dollars, but dont know how to, so that would be something else I could use help on.
