As expected, the contractor came back to us saying they'd like a bit more time.
Literal
Plan-as, that contractor [topic-は], time [subject-が] a-little-more want, [quotative-と] say-[come-toward-てくる]-[past-た].
Three notable pieces: 予定通りに ('as planned / as expected'); 業者 ('vendor, contractor, tradesman') — a common business word for a professional supplier; and 言ってきた, where ~てくる marks the speech as directed toward the speaker ('came saying,' 'reached out to us'). The embedded quote 時間がもう少し欲しい is the contractor's own voice, marked by the quotative と following it.
