Countertop Installer Called

I spoke with the countertop installer today and he's going to check the place out on Saturday. I asked if he would still be able to get the job done by the 15th, like the cabinet guy told me, and he says he thinks so. Apparently, it's just a one day job. He might be able to install sinks and plumbing at the bathroom vanities as well, but he's not sure. He said if he could get it done in one day, he would like to, since he likes the extra money, but he's not sure until he sees the job. So I'm going to plan on him not installing them.
