Create Email List from Web Sources

We need a quick turn-around on this project. Using specific web sites provided by us, provider will insert (copy and paste) the name, email, telephone number, and title of one particular person (Recruiting manager/Director of Recruiting) at 300 companies listed on a provided spreadsheet. One website (we will give you the link) contains a database that has this information most of the companies--so most searches will be done using this one particular service. Also, some of the companies will have more than one office (like New York, Chicago, Houston, etc.). Provider will add new rows and fill in information for each office--only if the recruiting person is different for each office. This is straight-forward.
