557152 sql server to xcart db migration

I need a script to export data from a custom shopping application database into a file suitable for uploading into an xcart shopping application using the xcart admin area import tool. The job will require analysis of the source database to understand how to map from the source to the target, including, products, product categories, product types and any other relevant product data that xcart can use. I am using xcart version 4.4.5. The source database is SQL Server, I can provide a backup to work from. I can also provide access to a development xcart version if necessary, though it would be preferable if you can use your own. This job is suitable for someone with previous xcart experience and I will favour those who can demonstrate such experience.
