Magento daily product import process needed

We are in need of a daily process that will import a number of CSV files. We can create the CSV files in any format that you need for the import process that you will build. We need a process that will be able to import a number of CSV files everyday automatically without any operator intervention. The process will need to be easy to add additional CSV files in the future when more products are added to our business. All products are Simple products in Magento and will require image import also. If you do not know magento import procedures then do not apply. Please include some import processes that you have worked on already so we can see what you have done.
