Custom XML product feed for Magento site

I need a solution for this fast. Within 1-2 days. For my client who has a Magento website: [login to view URL] I installed the add on: [login to view URL] To get some products feeds. There is one product feed which is not working correctly: [login to view URL] There are various problems with certain fields not appearing correctly. And there are some custom modifications which need to be made. You may be able to solve this by changing the settings or script of this add on. But I am not sure it is possible to adapt this add on for these changes. If this is not possible, then you will have to create a custom script to create this xml feed. The other problem is that the daily cron to renew the feed does not work. And this needs to be solved. I will email you the details as soon as we have an agreement to do the job.
