Database entry

I have a newsletter we send out each month. There is a natural attrition of the database numbers due to personnel movements and unsubscribers. So I require a regular supply of new names to replenish the database each month. This is a minimum of 400. Here is what I am looking for: 1. 400 new names each month from selected websites I supply 2. I will supply the website addresses for sourcing of the names for the creation of an uploadable list of names in Excel format to our data base 3. The Excel format will have 8 specific fields to be fulfilled from the websites I supply. These fields will be 1. First (Christian) name 2. Surname 3. City 4. State 5. Postcode 6. Mobile telephone number 7. Landline telephone number 8. email address I would pay on the basis of each name delivered in the Excel document. Can you give me a figure based on the price of each name delivered? Thank you
