What are the speakers mainly talking about?

M: I think it’s great that the company is obtaining so many new contracts. Just this month, we’ve landed(54)three new commercial building projects. Management says they are expecting to get at least one more by the end of the quarter.
W: That sounds good, but(53)we’ll need to hire some more employees soon. We’re already understaffed.
M: I’m not sure how many new employees we can afford to hire, but(53, 54)we definitely need more people in the engineering department. We could also use more people in accounts section, but I don’t think we can afford to hire for both departments.
W:(55)I think we should just hire for the engineering department for now. We have to get these projects started, so we don’t miss our deadlines.
