Automating Capturing & Processing Orders from Partner Websites and Creating OpenERP Invoices

We are into selling Auto Accessories online in India through our partner websites - [login to view URL], Flipkart, SnapDeal, [login to view URL], ShopClues, Tradus, PepperFry, etc. Currently we need to manually login into each partner website's seller portal and then do all or some of the following (depending on the partner website): - Check For New Orders - Accept Order - Print Order Details - Copy Information (like buyers name, address, pincode, email id, mobile number, product, quantity, price, shipping details, etc) - Create a sales order in OpenERP using the above information We want to automate this process entirely / partially. We can provide you with a step-by-step guide of the entire process for each of our partner website. The cron/script should be able to run at pre specified interval (eg. every 2 hours) also it will be great if it can save/email some kind of report after each execution/run. We are open about the language used for programming but it should ideally be executable from our CentOS based web server / hosting.
