A programme for assessing the content of web portals.

A programme for assessing the content of web portals. Description: I would like to create a tool which will evaluate the number of e-mail addresses present on ad portals. I would like the programme to search the whole portal and then give the number of e-mail addresses appearing on the portal. The programme is to be universal and work on different websites. The objective: To assess whether it is worthwhile to undertake the scrapping of a given portal in terms of obtaining e-mail addresses (e.g. by writing a dedicated scraper). Example of action: As a user, I enter two variables on the input: portal address (e.g. [login to view URL], [login to view URL], [login to view URL], etc.). The program itself finds subpages with company/person/product data. It then checks on each found subpage if there is an e-mail address. When it has already scanned all the subpages, it gives as a result of its actions what % of the pages contain the e-mail address and how many e-mails it has found in total on the whole portal. Conditions to be met: The program cannot scan the same subpage more than once. The programme cannot take into account the e-mails in the footer of the subpage, which belong to the administration of the service. The programme may be written in any language. The programme need not have a GUI The programme should be as universal as possible, i.e. it must not require too many changes to the various portals The program should be accompanied by an instruction manual with screenshots I would like the programme to be implemented on my vm (I leave the OS to choose) The programme and its working process should be lighter than standard scraping tools or dedicated scrapers, as the aim is only a preliminary assessment of potential Please include in your offer: Initial valuation Estimated implementation time Method of order execution
