EXPERIENCED PROGRAMMER NEEDED to access [url removed, login to view] API and extract data as outlined below.
1a) Initial Sign-In and Authentication of AWS/ A2S/ Amazon Product Advertising API using Access Key and Secret Key ID.
1b) Initially, program should download from Amazon to Excel (.xls - 2007), within a user defined Amazon category (ex: books, music, electronics, dvd, video games, etc.), and within a user defined Amazon sales rank (ex: 1- 20,000; 100 - 1,000; etc.) the:
1) Amazon Title
3) Item Sales Rank
4) Number of New Sellers
1c) Subsequent program runs should utilize all previously stored Excel ASIN's to return updated number of New Sellers to relevant, subsequent Excel columns.
2a - c) Essentially the same program(s) as above, except returns the number of Used Sellers.
Considering the amount of user defined information required, an easy user interface "dashboard" panel or window would be preferred (Windows XP).
Additionally, the program(s) should include a generous number of code comment lines giving line explanation. Also, the program should return various failure messages when unable to complete each step.
The setup instructions of the program should also be documented.
Succesful completion could well lead to additional similar program requests in the near future. Payment is for complete copyright of program and is made upon succesful first use by buyer.
I am easy to work with and am open to suggestions or questions. Thanks for your consideration and bids.
