Customize a Product Feed module for my Opencart website

Our Budget is R500. Our business is still small so we cannot go much higher than this at this stage. I need a product feed set up to Sync my items between my website and an online shopping website ("Bidorbuy"). Bidorbuy already has a module for this as well as documentation on how to set it up, but we have been having issues with our items not exporting - so we need someone to fix/customize the product feed for us. Currently what is happening is that our items are not exporting at all - the script runs, but the feed is empty. I can provide the module and relevant information on request, but due to their format they can only be supplied via email.
