Data Collection Project

Hi, I am looking for someone to be able to collect data from various websites I give you and build a database for me of peoples names, phone numbers and email addresses that I can use in my business. I need as many details as possible. For instance, one of the websites has 6000 people signed up to it so would Ideally need all of those details putting into a database. I need the details of people working in the financial services industry in the UK. I also need the details of local businesses in one city in the uk. Please give me a breakdown of the cost to do this and what you are willing to provide. thanks.
