Hello,
I can take care of all the functions you've presented in about 3 weeks including testing and clearing possible bugs. From my understanding you want the possibility of using the Amazon's API but also the functionality of scrapping the web pages through proxies, right?
Contact me if you are interested in high quality works, communication and reliability... I've studied in US 7 years, I am great with research and understanding my client's instructions. I go over requirements to obtain the best results time after time.
More about me... I have over 10 years experience in advanced data extraction, analysis and mining, including server administration [Linux, Solaris, FreeBSD], database creation, Excel works, web development [ PHP, Perl, Python etc ]
I am eager to take your project and provided with clear and thorough specifications, I will certainly deliver the best results possible.
Thank you for your consideration,
Radu C
