I know many people here charge $150/hour. 15k/week for two persons working 40 hour each is about $187/hour which doesn't look unrealistic to me. That's not to say they're cheap, they certainly aren't, but if you consider that a company has many expenses beside employees salaries then it's not that high.

Perhaps the biggest thing here is that you must hire a pair, so it actually comes to about $374/h, but if it's true that you get the job much more quickly with a pair then I don't see the issue.
