Auto updating financial web-database

Startup looking to build database: Creating an auto updating financial database for equities, derivatives, debt and mutual funds from freely accessible web pages. Scrape web pages to retrieve desired data to complete historical as well as for future runs along with an export to .csv format on every update. Data sizes: 5,000 to 10,000 entries (some follow common patterns, minimal repetition) Being a startup, such opportunities would come often and an efficient and enthusiastic response would be kept on an extended engagement for future projects (other scope areas as well).
