Hello,
My name is Rui Pimentel and I've more than 6 years of experience in development of web crawling applications.
I couldn't completely understand what you need from your project description, but I'm an expert on this area, and have powerful servers that can handle a lot of data, so I'm sure I should be able to retrieve all the information in less than 7days.
If you wouldn't mind to explain me more details about the project, I would be happy to work for you on this, and I can even provide you a demo in proof of my skills.
I'll be waiting to hear from you, and I'm looking forward to work for you on this.
Best Regards,
Rui Pimentel
