Planning scientific experiments

Sometimes I read things like this:

We estimate that for a 6-finger protein recognizing an 18 bp target site, the cloning can be performed in about two weeks or less by a skilled molecular biologist, especially if the two 3-finger subsites are cloned in parallel and assembled in the final step.

As a chemical engineering grad student, what I really want to know is how long does it take an unskilled molecular biologist? Guess we'll find out.
