Need Ebay Search Software: must pass Ebay's Compatible Application Check

Avg Bid (USD)
Project Budget (USD)
$250 - $750

Project Description:
I need a software program that will use Ebay's finding API to search for ebay listings that meet specific criteria.

The listings will be returned in the program in a specific format as described in my mock-up. This software program will need to be able to submit 50,000+ API calls a day so the software must be designed to pass Ebay Compatible Application Check. Once, the program has been developed, I will need the freelancer to submit the program to Ebay for their Compatible Application Check, and to correct any incompatibilities Ebay finds. The job is not complete until the program has passed Ebay Compatible Application Check, allowing me to make 50,000+ call a day.

DO NOT apply if you are not familiar with the requirements of Ebay's Compatible Application Check.

Please view the attached mock-up for a detailed description of how the program should operate, and how the UI should look.

This program will only be used internally.
