Amazon MWS script / XML feeds to add/delete/update products

I'm looking for example XML feeds for Amazon MWS to do the following: Add product (including all parameters/characteristics) Delete product (by SKU or ASIN) Update product (by SKU or ASIN) I already have an application in PHP that provides the Amazon API which currently updates quantities and prices. You can substitute your own PHP script, but it's not required. For someone who has already done this, it should be about 5 minutes of work to copy and paste an example feed of each. No bids over $100 will be accepted. Must have own website, Amazon account, etc. to demonstrate functionality. Or send XML code and participate in online meeting to debug if necessary. This is a re-posting of a previous job.
