These Guys are awesome! Over the past 3 years, I've used their services dozens of times > Fast-turnaround, straight-forward pricing, communicative in real-time (alerts you if your render setting will create a ridiculously long render time), worked with me over weekends, easy Dbox project management. When you are in the hot-seat and need a true partner to get your project render(s) done - I can't say enough about how much confidence you can have in http://www.3dotp.com/ delivering.

I've only had good experiences with these guys and their responsiveness is great!
