Description

I'm looking for someone to develop a desktop application for ebay product analysis. The application will essentially scrape completed listings based on my keywords, and provide an analysis of the results -- % of sold products, avg price of sold goods, etc. It can also be customized to include results only from a certain country, and only in "new" condition.

If this application works well, the application will be expanded to scrape data off another website, automatically search based on the keywords scraped on the other site, and also automatically compare cost->avg. sale price -- finally outputting a list of feasible products.

I'm from Australia -- so obviously it all has to work with eBay Australia!

The following is what a typical search results look like when you type in "iphone" and select the category "Mobile Phones": http://phones.shop.ebay.com.au/items...1QQ_sacatZ3312

On the left, you'll notice that there are other options, including: Completed Listings Only, Items from Australia Only, etc. What I need is an application that is fairly customizable with its scraping -- I type in a keyword, it then scrapes the completed listings. I also want it customizable, so as I can select a category (this is all plausible through eBay's regular navigation) if I want, or Australia Only if I want.

It then needs to generate some sort of report based on this -- highest price of completed sales and its description, lowest price of completed sales and its description, avg. price of completed sales, % of successful sales and avg # of successful sales per day.

Successful sales are shown in green on the completed listings page, and unsuccessful sales are shown in red. For now, as I've stated, I'm only interested in the successful listings.

So -- to stick with the theme of an iPhone:
I search "iphone" in the ebay program, and I can then select a category (I need to narrow it down so I include only iphones, and not the accessories for them) and I can select Australia only (as obviously there's quite a lot of things coming from Hong Kong which are illegitimate and are irrelevant to the information I need). It generates a report.

Here's our hypothetical 5 listings over, say, 2 days:
599.95 (sold)
650 (unsold)
610 (sold)
550 (sold)
570 (sold)

The program will interpret that they are sold obviously by the colour of the price (green = sold, red = did not sell). It will then calculate:
Avg Price of Successful sales = 599.95 + 610 + 550 + 570 / 4.

The rest should be fairly self-explanatory!
