Massive records must be consulted in a website

I need to keep my operations department up to date with information that can be obtained from a web site. You have to be able to get all that information in the less time possible and send us back the information requested. We'll provide an excel or xml file with the data required to fill the form for each record. The fields are: - City (Select list) - Entity (Select list. Values depends on the previous City selected) - Record Number (numeric field 23 digits) - Captcha field (Math captcha, the operation is an addition of two numbers, one or two digits operands “NN+NN”) Get the HTML text of the page with the query results. Send us back an XML file with all records completed via e-mail. Estimated Records to be consulted: 6.000 We require professionals in web scraping with proved experience, and able to use multi proxies and multi threads. More detailed information, documentation and data samples will be sent private. Depending on the accuracy and efficiency you will be rehired, since this is a recurrent task that must be done frequently Monday to Friday, day through or maybe daily basis.
