I am looking for someone who already has experience with Oscommerce and knows what they are doing. The version that I have is Creloaded 6.1. It has everything integrated but I need some programming and tuning done that I don’t have time for. Tasks (In Progress): 1) complete package tracking contribution integration. 2) Complete integration for split page results contribution. 3) create script to download a csv file and upload it to the database automatically -also to update the quantity in the original products table with the uploaded one.(needs to be scheduled) 4) create script to check if a csv file has "Price Drop!". If it does, to update then product price in a table with a given formula.(specials) 5) Create script to check if a csv file has "New". If it does, to display it in a report and add the item to the database much like "easy populate" contribution.(new Products) 6) create script to check which products have been ordered the most and place them as with status "featured" in the database. If no products are available, pick by random. 7) Adapt the specials infobox to fit into a new box at the bottom of the page. 8) Fix Information box not linking right because of Session Id. The person who gets the job must !DOCUMENT EVERYTHING!. Please note that these tasks must have a presentable front-end. Details will be provided to the winner. This project needs to be completed within 10-25 days, sooner is better. Bid ONLY if you are able to complete the project at the selected budget. The lower you bid, the more likely you will get the job. I am constantly in need of various programming, meaning if the person does a good job then they will get extra business from me. Budget is around $200.
