Automatically Publish Amazon and eBay Products to Wordpress Posts Using API

I have accounts/API keys for the eBay Partner Network and Amazon Associates Program (Product Advertising API). I want targeted products (in a specific category or theme) automatically formatted and published as Wordpress posts on my website. I am currently using the FeedWordPress autoblogging plugin, so I can automatically publish these products with RSS feeds. I am also open to a custom plugin or other solution--let me know what you can do. If you create RSS feeds, I would need them automatically updated with products (men's clothing and accessories) that are automatically coded/tagged with my account information. The feed items should be cleanly and uniformly formatted with a clean headline, image, post content and link. I'm open to a custom plugin or any other solution you can develop. Ultimately, I want monetized posts automatically created and published on my Wordpress site.
