You can try buying traffic from Choker and make a profit, but how about submitting regularly to the larger TGPs using
Advanced Submitter . It may take a month or two to be accepted at the larger TGPs, but if you perserve, and produce good galleries, you should get a lot of traffic.
If you are starting out, then I suggest submitting to TGPs first, until you develope your design skills, and only then buy traffic from Choker. Otherwise you could waste a lot of money unnecessarily.
