Develop inventory sync for multile sites

I need to take my inventory from my amazon listings and somehow get them listed/synced with [login to view URL], [login to view URL], [login to view URL], [login to view URL] and preferably my own .com. I do have the automfc which will allow me to keep the inventory synced up once I get it listed. The file should to be able to extract my amazon inventory and be able to use the file to list the same items on these other sites - with Images to use with 500 minimum pixels on one side minimum which will be up;oaded as perhaps a new sku file to each site. If it were easy to add new inventory to this ?csv or flat? file even better. It would be great to have the ability to price match and compare selling prices as well. If you think of something else that would make syncing this inventory easy feel free to let me know. I am a one man operation and need to speed this process along plus at a reasonable rate.
