Amazon.de MWS / AWS upload articles and download the current stock

Hello, we need some [login to view URL] specialist. We have a php script which load the current stock, but the fba article will not be updatet in our database (why?) - this should be fixxed. 2. The rank and the category should be saved in database (of the product) 3. there should be a textbox where we can insert an asin from amazon -> click on search the script will generate a list of child variation of this asin The list should have these cols. Checkbox | name | variation | best price | asin | sku (if we already offer this variation) Then if i select the checkbox = TRUE the script upload these articles to amazon (so that we offer them too) The price should be same like the best price. Quantity always = 1. Then the script must tell me which new sku the uploaded variation has and save them into mysql database. 4. If i insert a sku the script should move the article in Amazon to "FBA" or "merchant" Shipment (i can choose with a option box). Thanks Waiting for your offers. Skype for communication is best.
