Emails/contacts collection / Data entry

Hello there! I am looking for someone who could help me with extracting data from a website. There is a property (=real estate in British speak) listings portal. I will need to make a search for all properties in some particulal location. It will give maybe 1000 resuslts. I want you to go through all these 1000 listings and create an Excel document with link to listing, name of agent advertising it, phone number and email of the agent. Some agents have their emails on the website, for some you need to put their name in google and find it on their own website. All these 1000 proeprties will be advertised by maximum 100 different agents, so really you only need to find details of 100 agents. Please give me your best quote for this job. If I like your work, there is a possibility of lots of follow up jobs, including sending emails, calling, and more email/contacts collection.
