Overall description: (see attachment for more detail) I am going to build a system to collect some data from websites. I would like to use AWS, open source frameworks for this purpose. My background: - Graduate the university of Information technology. - Already learn the can do a separate python code to extract a specific website in python, save the result to text files. - Doing web crawling on AWS, using framework, storing result in NoSQL database is totally new to me. I would like to have an expert to: Guide me to do the thing onetime, so that I can develop the detail (such as add more urls, writing more code for new format of new urls, adding more fields to database). All the steps are started from standard material, so that I can follow to build the system by myself after I understand the mechanism. Do not need to explain me the concepts, I can Google to study if I do not understand. I just need the steps to understand the foundation.

Dear Sir, I have reviewed your job requirement carefully and then excited. I have rich experience in scraping application for AWS. I have just delivered such a job to client from US recently, so I have already app to do it. It is written as C# not python. I recommend this app because speed is very fast than others. Let's discuss further detail. Sincerely, An

I read your requirements and I was happy to see that this is exactly my area of expertise! You did a good choice by choosing the scrapy framework. It is very stable, easy to learn, and fast! There is one alternative, called selenium framework, which allows to control a normal webbrowser from python, so it is helpful to scrape sites with high security measures. But on the sites you mentioned it shouldn't be needed. The timeline you've chosen seems very appropriate for this project to go smoothly. I say I deliver in 5 days, but thats just steps until step 3. After that you can take as much time as you need. I will give you support with any question relating to this project for as long as it takes. I'm eager to start! Hope you choose me, you won't be disappointed.
