If you are one, I may have a job for you right now. Post here if you are one and I will send you a PM.
You may also buy the DRT tool if you would like to scan on a daily basis whole lists of dropping domains. good luck
I heard that Pool.com has the best success rate of grabbing an expired name - but they also charge more.
If you're looking for someone who uses snapnames to the tune of tens of thousands a year as a "domain catcher", there are plenty of us. If you're looking to actually speak to someone at Snap or Pool, that can be arranged as well... What's the purpose/info?
