Wayne Crowe has been in the industry for more than a decade and has solid traffic. His traffic can be accessed by signing up here:

This is a great resource where you can find reputable sellers. This place is managed by Harris Fellman who has been brokering and emailing for more than a decade now and focuses on the Biz-Opp, Internet Marketing, Self-Help niches and etc… Traffic is old on a CPC basis which is great for us

Although these are the places I’ve purchased traffic to build my email list you must be careful and only contact sellers who have proven to provide sales to their clients. Read the reviews, contact them and communicate with them. It’s very easy to get scammed from vendors who promise to sell you “High-Quality Traffic” but end up serving you bot clicks.Do not buy traffic from vendors who approach you! Only buy from reputable sellers!
