Wordpress plugin and affiliate API integration

Hello,

I need a wordpress plugin adding to my site along with an affiliate API integration. Experience in producing wordpress plugins and working with affiliate APIs like Amazon web services and Affilaite Window productserve is preferred. Fixed fee only. 2 weeks development time max.


Requirements:

WordPress plugin to add a form which allows logged in users to add posts.
Integrate two affiliate APIs into a dropdown list of merchants so users can select a product.
Add chosen product data to post as custom fields along with the standard post fields.

The plugin form will work in a similar way to this plugin capturing title, content and image upload:
http://wordpress.org/extend/plugins/wp-user-frontend/

There will then be a dropdown list of merchants who are listed on two affiliate schemes. The user selects a merchant, browses for a product using the api and then selects the one they want. At this stage I want to integrate the Affiliate Window product serve API and the Amazon Affiliate API so Amazon should be included as a merchant in the dropdown list along with the merchants on affiliate window. In future I may need to add other affiliate schemes to the system.

http://docs.amazonwebservices.com/AWSECommerceService/latest/DG/Welcome.html?r=3950

The following information will be called from the API and stored as part of the post:
product name
product image
merchant name
product description
affiliate link

I have already included places for this info in my template so the single post template will need updating to use the stored api data where required.



Thanks

Steve
