Hello,
(you specified a minimum $250 bid. For the current amount of data, I can sell for $150)
I have collected a database for your project. A ready database contains 3,300+ restaurants in NYC with emails (all emails are unique). Actuality - today, source - own pages of restaurants on the web.
Email is a hard thing to mine. Overall there are more than 16,500 NYC restaurant venues in the database having up-to 20 fields: address, lat/lon, description, open hours, phone number, website, etc. This is about 40% of all NYC restaurants. The restaurants are also categorized by borough (Manhattan, Bronx, Brookline, Queens, Staten Island)
The database also includes categories of restaurants for rich taxonomy (e.g. Italian restaurant, Mexican restaurant, etc).
If you need more, it's possible to collect more restaurants. It is also possible to collect restaurants from other cities.
If you are interested in I can provide you with a small snapshot of the database.
