Eventective is one of my favorite lead generation engine sites for DJ gigs in the TriState area. The website was launched in 2003 to help customers find the perfect space for their events.
The site sends professionals a list of lead prospects along with the client's phone number or email, details about the event (type, people, date, location, budget, etc), a snippet of your last message to the lead, and if the lead viewed the message or not. Additionally, once on the specific lead page, everything is recorded, from clicking on the phone number to sending emails.
The best part about Eventective is that you have two options for buying leads: pay-per-lead, which, as of writing this post, costs $2.50, or you can subscribe to a variety of subscription options that offer different levels of marketing and even a 25 cent pay-per-click option.
I'm a big fan of Eventective, and recommend it to other event vendors. It would be hard to find a more affordable and effective website in the event planning industry.
