Dear Sir,
As an experienced web developer, I am really willing to work with you.
I can scrap any data from any website.
Captchas, Ajax, Javascript or any other technology is no problem.
Most of my work is done with Python's Scrapy framework but I know Perl, PHP, C#, Javascript and Java.
Also, I have experience working with DBMS such as MySQL, PostgreSQL, MongoDB, MS SQL, and Access.
I have completed several hundreds of web and desktop automation projects (data scraping, mining, and processing).
I am ready to start work immediately and please let me know if you have questions.
I would like to point out that my bid amount is simply a guide and is always open to negotiation.
I understand that you have a very generous budget, however for me personally the money is not my motivation, it's the opportunity to have my hard work noticed and on display for others to benefit from and enjoy.
I would welcome the opportunity to discuss the project in more detail and very much look forward to working with you.
Thank you for reading and consideration.
Andrei.
