Data Mining

I have a database of approximate 1500 entries, with names and US based addresses. Some are companies - most are individuals. I wish to reverse append the data with contact numbers and where possible email addresses. The project will require data mining. I will package up the entries into parcels of 500 or so and pay 20 cents per matched telephone number and 30 cents for phone and email. Please note some entries may not be matchable to a telephone number and the data you provide will be randomly tested for accuracy before payment is released. You are welcome to return the appended data either in one batch or in parcels and request milestone payments accordingly.
