Need a star web scrapper (experienced and sharp)

We are a startup and looking to scrap certain information that is publicly available. We are looking for someone reliable and as go to person for web scrapping. You will only be responsible for developing and testing the tool. We would scrap data from our servers. Preferred methods would be python with scrappy framework, but we are open to suggestions. We would also need some further consultation, hence you must have expertise. Estimated project price is subject to change based on the discussion, and further agreement. In your proposals, please include information about what methods/tools do you use for webscrapping, and why it is best and fast.
